# Spanish/Tenses
## 1. Vocabulary used in this section:

* Infinitive:
** It is the original form of a verb.
** It ends in "-ar", "-er", or "-ir". (Verbs with the ending "-ír" are included in the last group.)
** The example infinitives used in this section are: hablar (to speak), comer (to eat), and vivir (to live).
       These verbs will be used to show the conjugation patterns of the "-ar", "-er", and "-ir" groups, respectively.
* Stem:
** The stem of a verb is the infinitive without its "-ar", "-er", or "-ir" ending.
** In most conjugations, a new ending is attached to the stem (future and conditional tenses attach the ending to the infinitive).
** For instance, in the first person singular of the simple present indicative hablar:
       $\mathbf {habl} \mathrm {ar} \quad \Rightarrow \quad \mathbf {habl} -ar\quad \Rightarrow \quad \mathbf {habl} +o\quad \Rightarrow \quad \mathbf {habl} \mathrm {o}$
    This forms, hablo (the first person singular of the simple present indicative of the verb hablar), which means "I speak".

## 2. Conjugation of the verbs
### 2.1 A basic understanding of the layers to the conjugate

The verb describes action. The 'thing' performing the action is the subject, and the 'thing' on which the action is performed is the object.
The verb is conjugated to demonstrate the action, and the correct conjugation can only be selected after the writer, or speaker, has analysed several layers relating to the action, the actor, and form of expression required.
There are seven basic layers in determining the correct conjugate. They are: the language the verb, the form, the mood, the tense, the subject, and the conjugate.
Some of the basic layers contain layers before we reach the decision point and these are: the verb, the tense, and the subject.
The verb layer contains the following sub-layers: the verb, the regularity, the basic conjugates, and the verb group [verb groups are not used in English].
The tense layer consists of these sub-layers: style, time, and variants [tense variants are not used in English].
The subject layer is simply: the plurality, and the personage.
Let's end our consideration of the basic layers with a simple example.
Table: demonstrating the layers to a conjugate of the Spanish verb 'hablar' with a comparison to its English equivalent:
Note 1: In this text we are considering Spanish from an English speaking perspective. So, we have two languages: Spanish and English. The comparison is illustrative to the new learner English speaker; so, both will be considered here.
Note 2: The new learner should use this example in the following table as an illustration of the steps required to reach the desired conjugation, the decisions, especially the Spanish words, will become clearer as you read on.
| | Layers | Decision | Decision |
| 1.1 | Language | Spanish | English |
| 2.1 | Verb: | hablar | speak |
| 2.2 | Verb, regularity: | regular verb | irregular verb |
| 2.3 | Verb, basic conjugates: | infinitive: hablar stem: habl- participle: hablado gerund: hablando | infinitive: to speak root: speak participle: spoken gerund: speaking |
| 2.4 | Verb, group: | "ar" | not used |
| 3.1 | Form: | nominal | nominal |
| 4.1 | Mood: | indicative | indicative |
| 5.1 | Tense, style: | simple | simple |
| 5.2 | Tense, time: | past | past |
| 5.3 | Tense, variant: | preterite | not used |
| 6.1 | Subject, plurality: | plural | plural |
| 6.2 | Subject, personage: | 3rd person | 3rd person |
| 7.1 | Conjugate: | hablaron | spoke |

### 2.2 A greater understanding of the layers to the conjugate

In the previous section we demonstrated the 'basic' layers, or steps, to arrive at our conjugate for both the Spanish and English languages. In the Spanish language there were 13 steps, in the English 11 steps: as noted, the English language does not use the 'verb group' or 'tense variant' layers.
Let's now consider the choices available at each layer, and in doing so let's stick to the order in our example, set out in the table in the previous section.

#### 2.2.1 Language layer

It has been noted above, but we are considering the Spanish from an English perspective, there can be only two choices in this instance: Spanish, and English.

#### 2.2.2 Verb
##### 2.2.2.1 The verb

We need a verb to conjugate, so the need for the layer is obvious, we are restricted only by the number of verbs in the languages we are considering. There are very many in both the Spanish, and the English languages.

##### 2.2.2.2 Verb, regularity

There are two types of regularity to consider: regular verbs and irregular verbs.
A regular verb is a verb in which all the conjugations follow strict rules. An irregular verb contains at least one, usually more, conjugates which defy these rules. However, many conjugations in an irregular verb may still be regular.
The regular verbs allow us to use strict rules to form the conjugate. So, learning the sets of rules allows us to conjugate a very many regular verbs, and some regular conjugations of irregular verbs without having to learn a separate word for each conjugation. It also makes the conjugation of unfamiliar regular verbs less onerous.
The irregular verbs irregular conjugations require learning by rote. As do the rules for regular conjugations. Though, as noted above, irregularity may only be partial, much of the verb may follow the strict boundaries of regularity, making learning easier.
Many important verbs are irregular; for example: haber, tener (both: to have), estar, ser (both: to be). Haber and estar will be used in this appendix as auxiliary verbs in constructing complex tenses.

##### 2.2.2.3 Verb, basic conjugates

There are four basic conjugates: the infinitive, the stem/root, the participle, and the gerund.
The basic conjugates are listed in the example. Apart from the stem they had little use in the decision making process, but we are discussing conjugation of the verb, and it is useful to the learning process to start to recognise them in a basic form as early as possible

##### 2.2.2.4 Verb, group

There are 3 verb groups in Spanish: "ar" verbs, "er" verbs, and "ir" verbs. There are no verb groups used in conjugating English verbs.
Verbs come in 3 endings in Spanish, which are: "ar", "er" and "ir". Hence the 3 verb groups.
The rules one uses for regular conjugations, in both regular and irregular verbs, are entirely dependent upon which ending a verb has. The "er" and "ir" verbs often have the same, or similar, endings. The "ar" verbs usually have very different endings from the "er" and "ir" verbs.

#### 2.2.3 Form

There are two forms in both the Spanish and English languages: the nominal, and the continuous.
The nominal may be referred to in other texts as the basic form, and the continuous as the progressive form. In this text we will maintain a consistent single reference to avoid confusion to the new learner, at least.

#### 2.2.4 Mood

There are 4 moods in Spanish: the indicative, the indicative conditional, the subjunctive, and the imperative.
Many other texts will refer to only 3 moods (modos): the indicative mood (modo indicativo); the subjunctive mood (modo subjuntivo); and the imperative mood (modo imperativo). They treat the indicative conditional mood as a 'tense' used only in the indicative mood.
In this text the indicative conditional conjugations are treated as a mood group just as the imperative is treated as a mood, and not a separate indicative tense. Here, it is referred to as 'the indicative conditional' to remind us of the link to the indicative mood used by other texts on the Spanish language.
Why contradict other texts? The new learner requires order to the process of learning, this is the primary reason. By defining the indicative conditional as a mood it means the tense layers can be considered a homogeneous group relating to aspects of time only. It's clear the indicative conditional is not a reflection of time, it more closely reflects a mood, one influenced by condition, or conditions. Does that not define a mood? An expression of 'emotion' defined by conditions. And so, we maintain homogeneity of the mood layer too, making the learning process easier to the newcomer.
In the imperative mood there exist conjugations for both:
* the affirmative, and;
* the negative.
The negative in the imperative is not formed in quite the same way as the other moods.

#### 2.2.5 Tense

It is unlikely you will see tenses broken into three separate groups in other texts regarding verb conjugation. I believe it is easier to think of the tense decision making process as a matrix rather than a list which is named differently in each text. This is best demonstrated with a table [a matrix].
| Tense, style | simple, or perfect | simple, or perfect | simple, or perfect | simple, or perfect |
| Tense, time | Past | Past | Present | Future |
| Tense, variant: | Preterite | Imperfect | No variant | No variant |
As can be seen the simple 'style' and the perfect 'style' are identical tables, which makes remembering the choices for tense a clearer process for the new learner.

##### 2.2.5.1 Tense, style

There are two styles: the simple, and the perfect.
The perfect tense style describes a completed action. The tense layers following describe the aspect of time in which that action was completed.
The participle of the action verb is always used. In addition an auxiliary verb, have, is adjusted in the simple style, based on time and variant to reflect the time of completion: past, present, or future.
For examples: Perfect style, past time: 'I had spoken' is describing the completed action of speaking using the participle: 'spoken' of the action verb: 'speak' with the auxiliary verb: 'have' in the simple style, past time: 'had'. Perfect style, present time: 'I have spoken': action verb: speak; participle: spoken; auxiliary verb: have; simple style, present time: have. Perfect style, future time: 'I will have spoken': action verb: speak; participle: spoken; auxiliary verb: have; simple style, future time: will have.
WIP EDIT NOTE: REGARDING SPANISH

##### 2.2.5.2 Tense, time

Three possible times: the past, the present, and the future.

##### 2.2.5.3 Tense, variant

In Spanish only the past has variants. There are two variants: the preterite, and the imperfect. There are no tense variants in English.
Translation of both to English uses the tense, time: past.
The preterite tense variant does not exist in the subjunctive mood.

#### 2.2.6 Subject
##### 2.2.6.1 Subject, plurality

There are only two choices: singular, and plural.

##### 2.2.6.2 Subject, personage

Three decisions here: 1st person, 2nd person, and 3rd person.
Note: for the imperative mood each verb may be conjugated for only 5 different subjects.
It's worth noting here which 5 subjects apply. Obviously, we cannot issue commands to:
* singular, 1st person: 'I' (yo);
* singular, 3rd person: 'he' (él) or 'she' (ella); or
* plural, 3rd person: 'they' (ellos [masc., or mixed] or ellas [fem.]).
However, because Spanish uses a formal 2nd person form, singular and plural, the singular and plural, 3rd persons still apply: the formal versions of 'you', being the singular, 2nd (usted) and the plural, 2nd (ustedes) use the 3rd person endings depending on their plurality. This means only the 1st person singular is not used.

#### 2.2.7 Conjugate

Many of the steps result in identical decisions, making the conjugation paradigms for both languages very similar. This is encouraging for the new learner. However, it would be wise to note that in the above example the decision in the conjugate layer for English would be the same for every single choice available for the subject layers, yet the decision for the Spanish conjugate layer would not. Let's demonstrate this with a table which represents the choices available when we change only the 2 subject layers: 'plurality', and 'personage'.
Table: demonstrating the variety of choice in the conjugation decision layer in the Spanish language compared to the English language.
Note 1: The conjugates displayed in the table below have exactly the same decision layers as demonstrated in the table, in the previous section, demonstrating the basic understanding; i.e. for the Spanish language: the regular verb 'hablar' from the "ar" verb group with basic conjugates: 'hablar', 'habl-', 'hablado', 'hablando'; in the nominal form; indicative mood; simple style, past time, preterite variant tense. And, for the English language: the irregular verb 'speak' with basic conjugates: 'to speak', 'speak', 'spoken', 'speaking'; in the nominal form; indicative mood; simple style, past time tense.
Note 2: Again, the new learner should look at the overview rather than concern themselves with the Spanish translations; these will become clearer later.
| Subject layers | Subject layers | Spanish | Spanish | English | English |
| Subject, plurality: | Subject, plurality: | Singular | Plural | Singular | Plural |
| Subject, personage: | 1st | hablé | hablamos | - - - - spoke - - - - | - - - - spoke - - - - |
| Subject, personage: | 2nd | hablaste | hablasteis | - - - - spoke - - - - | - - - - spoke - - - - |
| Subject, personage: | 3rd | habló | hablaron | - - - - spoke - - - - | - - - - spoke - - - - |
EDIT NOTE: work-in-progress
Therefore, this gives us 20 [5 tenses in 4 aspects] indicative tenses, and 12 [3 tenses in 4 aspects] subjunctive tenses for each verb. Furthermore, for each of these 32 tenses, the verb can be conjugated for 6 different subjects: 3 in the singular, and 3 in the plural [see Spanish pronouns]. This means there are 192 conjugations for each verb in the indicative [120] and subjunctive [72] moods in total.
This brings our count to a total of 204 conjugations for each verb.
Luckily for learners, the vast majority of these verbs fit into well-defined and easy-to-learn categories. These verbs are called regular verbs, and our example set contains three regular verbs, being:
* hablar (to speak);
* comer (to eat), and;
* vivir (to live).

## 3. Non-finite forms
### 3.1 Infinitive

The infinitive of a verb is most often used after another conjugated verb like 'tener' (to have) or 'querer' (to want). The infinitive may also be used colloquially by Spanish speakers in place of a command, usually when left as a note to oneself to remember to do something. On web pages, one may also see buttons or links that use the infinitive, not the imperative form. The infinitive form contains the verb's stem followed by the ending.
Commonly used expressions with the infinitive:
To use these expressions, conjugate the first verb appropriately and follow with the infinitive. The first verbs in these expressions can be conjugated in any tense.
Conjugate of tener + que + infinitive means "to have to" do something. Example: Tengo que poner la mesa antes de cenar. Translation: I have to set the table before dinner [poner (to place, put, set, lay)].
Conjugate of querer + infinitive means "to want to" do something. Example: Ella quiere aprender inglés. Translation: She wants to learn English [aprender (to learn)].
Conjugate of acabar + de + infinitive means "to just have" done something. Example: Acabo de hacer la tarea. Translation: I just did my homework [hacer (to do)].
Conjugate of hay + que + infinitive means that something "has to be done". It is unspecified who has to do it. Example: Hay que darle comer al perro hoy. Translation: The dog needs to be fed today [comer (to eat)].

### 3.2 Past participle

The past participle is used with the perfect tenses, but can be used on its own as an adjective, most commonly with the verb "estar" (to be).
Example: Mi perro está perdido. Translation: My dog is lost.
Example: Estoy buscando mi perro perdido. Translation: I'm looking for my lost dog.
In this case, the verb perder means to lose, and the past participle perdido means lost.
Participles are formed using -ado for -ar verbs and -ido for -er and -ir verbs.
| Infinitives from our example set | Infinitive stem + ending | Past participle stem + ending | Past participle |
| hablar (to speak) | habl + ar | habl + ado | hablado (spoken) |
| comer (to eat) | com + er | com + ido | comido (eaten) |
| vivir (to live) | viv + ir | viv + ido | vivido (lived) |
When used as adjectives, past participles come after the noun and are modified by the number and, or, gender of the noun. Participles modifying feminine nouns will now end in -ada or -ida. To pluralize a participle, simply add s to the end of the adjective.
Table: examples of conjugation of verbs for use of past participle as an adjective.
| Infinitives from the example set plus one other | Infinitive stem + ending | Singular or plural noun | Past participle as adjective stem + ending for masc. noun | Past participle as adjective for masc. noun | Past participle as adjective stem + ending for fem. noun | Past participle as adjective for fem. noun |
| hablar (to speak) | habl + ar | singular plural | habl + ado habl + ados | hablado (spoken) hablados (spoken) | habl + ada habl + adas | hablada (spoken) habladas (spoken) |
| comer (to eat) | com + er | singular plural | com + ido com + idos | comido (eaten) comidos (eaten) | com + ida com + idas | comida (eaten) comidas (eaten) |
| vivir (to live) | viv + ir | singular plural | viv + ido viv + idos | vivido (lived) vividos (lived) | viv + ida viv + idas | vivida (lived) vividas (lived) |
| hervir (to boil) | herv + ir | singular plural | herv + ido herv + idos | hervido (boiled) hervidos (boiled) | herv + ida herv + idas | hervida (boiled) hervidas (boiled) |
Example: Las espinacas están hervidas. Translation: The spinach is boiled.
A feminine plural noun, 'Las espinacas' (the spinach), requiring a feminised plural adjective, 'hervidas' (boiled) [see table above].

### 3.3 Gerund

The gerund exists in English as the -ing ending and is used in the same way as English, with a few exceptions. Gerunds usually follow a conjugated form of the verb estar (to be) to form the present tense in the simple continuous aspect [normally referred to as the 'present continuous tense' or the 'present progressive tense'].
| Infinitives from our example set plus two others | Infinitive stem + ending | Past participle stem + ending | Past participle |
| hablar (to speak) | habl + ar | habl + ando | hablando (speaking) |
| comer (to eat) | com + er | com + iendo | comiendo (eating) |
| vivir (to live) | viv + ir | viv + iendo | viviendo (living) |
| andar (to walk) | and + ar | and + ando | andando (walking) |
| tocar (to play, to touch, to perform) | toc + ar | toc + ando | tocando (playing, touching, performing) |
Example: Ella está andando por el pueblo. Translation: She is walking through the village.
Gerunds are also often used with a conjugated form of the verb seguir (to continue) to mean 'to continue doing something' or 'to be still doing something'.
Example: Sigo tocando el piano. Translation: I'm still playing the piano.

## 4. Nominal form of the indicative mood

The indicative is the most basic mood, used to talk about actions, events, or states that are believed to be facts or true. It is very typical in speech for making factual statements or describing obvious qualities of a person or situation.

### 4.1 Simple tense style: nominal form, indicative mood
#### 4.1.1 Present tense: nominal form, indicative mood, simple tense style

The present tense is used to talk about actions, events, and states that happen generally in one's life, but is also often used to talk about actions that are happening right now.
| Examples | Translation |
| Yo monto en bicicleta todos los días | I ride my bicycle every day |
| Nosotros comemos unas bananas | We are eating some bananas |
Table: verb endings for the nominal form, indicative mood, simple tense style, present tense.
| Singular subject | Conjugate ending | Conjugate ending | Conjugate ending | Plural subject | Conjugate ending | Conjugate ending | Conjugate ending |
| Singular subject | "ar" | "er" | "ir" | Plural subject | "ar" | "er" | "ir" |
| yo (I) | -o | -o | -o | nosotros (we [masc., or mixed]) nosotras (we [fem.]) | -amos | -emos | -imos |
| tú (you [informal]) | -as | -es | -es | vosotros (you [masc., or mixed] [informal]) vosotras (you [fem.] [informal]) | -áis | -éis | -is |
| él (he [masc.]) ella (she [fem.]) usted (you [formal]) | -a | -e | -e | ellos (they [masc., or mixed]) ellas (they [fem.]) ustedes (you [formal]) | -an | -en | -en |
Example set:
| | The infinitive (El infinitivo) | Singular (Singular) | Plural (Plural) |
| Example ("ar") | hablar | hablo, hablas, habla | hablamos, habláis, hablan |
| Translation | to speak | I speak, you speak, he/she/one/it speaks | we speak, you speak, they speak |
| Example ("er") | comer | como, comes, come | comemos, coméis, comen |
| Translation | to eat | I eat, you eat, he/she/one/it eats | we eat, you eat, they eat |
| Example ("ir") | vivir | vivo, vives, vive | vivimos, vivis, viven |
| Translation | to live | I live, you live, he/she/one/it lives | we live, you live, they live |
Further examples:
| Examples | Translations |
| Tú hablas demasiado de tu hermana | You talk about your sister too much |
| Andamos por la playa | We are walking along the beach |
| Comen vegetales frescas | They eat fresh vegetables |
| El nuevo estudiante parece genial | The new classmate seems great |
| Vivimos en una grande casa cerca del centro | We live in a large house near downtown |
Forming the negative: Forming the negative is very simple in most tenses, especially the present indicative. Simply place no directly before the conjugated verb.
| Example | Translation |
| No escribo en un diario | I don't write in a diary |

#### 4.1.2 Past tense, preterite variant: nominal form, indicative mood, simple tense style

The preterite is used to talk about one-time events that occurred in the past and have already ended. It is absolutely necessary to remember the accents in both writing and speech.
| Examples | Translations |
| Yo nací en Zaragoza. | I was born in Zaragoza. |
| Ella conoció a su mejor amiga el año pasado. | She met her best friend last year. |
Table: verb endings for the nominal form, indicative mood, simple tense style, past tense, preterite variant.
| Singular subject | Conjugate ending | Conjugate ending | Conjugate ending | Plural subject | Conjugate ending | Conjugate ending | Conjugate ending |
| Singular subject | "ar" | "er" | "ir" | Plural subject | "ar" | "er" | "ir" |
| yo (I) | -é | -í | -í | nosotros (we [masc., mixed]) nosotras (we [fem.) | -amos | -imos | -imos |
| tú (you [informal]) | -aste | -iste | -iste | vosotros (you [masc., mixed] [informal]) vosotras (you [fem.] [informal]) | -asteis | -isteis | -isteis |
| él (he [masc.]) ella (she [fem.]) usted (you [formal]) | -ó | -ió | -ió | ellos (they [masc., mixed]) ellas (they [fem.]) ustedes (you, [formal]) | -aron | -ieron | -ieron |
Please note: the nosotros conjugation ending for -ar (-amos) and -ir (-imos) forms are the same in both past preterite and simple present tenses. Determining the tense in these situations will depend on context. This isn’t the case for -er verbs, which have the nosotros conjugation ending of -emos in simple present and -imos in preterite.
Example set:
| | The infinitive (El infinitivo) | Singular (Singular) | Plural (Plural) |
| Example ("ar") | hablar | hablé, hablaste, habló | hablamos, hablasteis, hablaron. |
| Translation | to speak | I spoke, you spoke, he/she/one/it spoke | we spoke, you spoke, they spoke |
| Example ("er") | comer | comí, comíste, comió | comimos, comísteis, comíeron |
| Translation | to eat | I ate, you ate, he/she/one/it ate | we ate, you ate, they ate |
| Example ("ir") | vivir | viví, vivíste, vivió | vivimos, vivísteis, vivíeron |
| Translation | to live | I lived, you lived, he/she/one/it lived | we lived, you lived, they lived |
Further examples:
| Examples | Translations |
| Nosotras jugamos un partido de fútbol la semana pasada. | We played a game of football (soccer) last week. |
| ¿Ustedes visitaron a sus parientes la navidad pasada? | Did you visit your relatives last Christmas? |
| Comí un trozo de pastel ayer. | I ate a slice of cake yesterday. |
| La maestra me asistió ayer. | The teacher helped me yesterday. |
Forming the negative Just like in the present tense, simply add no directly before the conjugated verb to negate.
| Example | Translation |
| No escribió una novela. | I didn't write a novel. |

| Translation | to live | I will live, you will live, he/she/one/it will live | we will live, you will live, they will live |

### 4.2 Perfect tense style: nominal form, indicative mood
#### 4.2.1 Present tense: nominal form, indicative mood, perfect tense style

To form the present tense in the perfect aspect of the indicative mood, combine the verb haber (to have), conjugated for the simple aspect of the indicative mood in the present tense, to the past participle for the verb in question.
i.e. haber (conjugated, indicative mood, simple aspect, present tense) + Spanish verb (conjugated in the past participle).
This tense is often referred to as the present perfect [of the indicative mood].
Example set: el infinitivo: hablar. Singular: he hablado, has hablado, ha hablado. Plural: hemos hablado, habéis hablado, han hablado. Translation: the infinitive: to speak. Singular: I have spoken, you have spoken, he/she/one/it has spoken . Plural: we have spoken, you have spoken, they have spoken.
Example set: el infinitivo: comer. Singular: he comido, has comido, ha comido. Plural: hemos comido, habéis comido, han comido. Translation: the infinitive: to eat. Singular: I have eaten, you have eaten, he/she/one/it has eaten . Plural: we have eaten, you have eaten, they have eaten.
Example set: el infinitivo: vivir. Singular: he vivido, has vivido, ha vivido. Plural: hemos vivido, habéis vivido, han vivido. Translation: the infinitive: to live. Singular: I have lived, you have lived, he/she/one/it has lived. Plural: we have lived, you have lived, they have lived.

#### 4.2.2 Past tense, preterite variant: nominal form, indicative mood, perfect tense style

To form the preterite (past) tense in the perfect aspect of the indicative mood, combine the verb haber (to have), conjugated for the simple aspect of the indicative mood in the preterite (past) tense, to the past participle for the verb in question.
i.e. haber (conjugated, indicative mood, simple aspect, preterite (past) tense) + Spanish verb (conjugated in the past participle).
This tense is often referred to as the preterite perfect [of the indicative mood].
