# Imperfect and Future constructs

Warning: Beyond the imperfect, this page is not entirely clear. Do not use it beyond the basic imperfect if you are a first time Latin student. See discussion for my thoughts on this.

## Imperfect Active Indicative

The imperfect is a construct like:
    I was seeing.
In Latin it would look like this:
    Vidēbam.
English has a similar construct called progressive past. Actions seem incomplete, and so the imperfect label. For example, "I was running," "We were sailing," "They were calling." Note that 'to be' is always there. Latin, however, would sometimes use imperfect like simple past; accordingly, "We were sailing" could be translated as "We sailed." Other translations of imperfect can be used to/kept such as "We used to sail/We kept sailing."
Regardless of language, the concept of an imperfect is important. Imperfect is called imperfect for a reason - in Latin, the verb "perficere" means to finish/complete, which is what perfect is from. Thus, imperfect, in the grammatical sense, means not finished - that the action could be or could not be completed. Perfect instead means it has been finished - I saw. You have already seen, and it is now completed. I was seeing implies that the action is not yet completed.
The perfect tense, which we will learn later, is a more immediate reference to the past. The name, imperfect, helps you remember its use: in situations where you can't say when an event started or ended or happened, you must use the imperfect.
In situations where you can know when an event started or ended or happened, use the perfect.
You conjugate the imperfect tense this way: verb + -bā- + personal ending
The endings for imperfect are:
Sg.
* -bam
* -bās
* -bat
Pl.
* -bāmus
* -bātis
* -bant
Note that the only thing we add are ba + the personal endings (the same as in the present tense) to the infinitive stem. This gives us the imperfect conjugation.
Note that in third and fourth conjugations, you will have to form it differently. There is *no* rule to explain this, it just is, although there are memorization techniques that can help.
venire is 4th conjugation and is formed like:
    veniēbam
    veniēbās
    veniēbat
    veniēbāmus
    veniēbātis
    veniēbant
For third conjugation -iō stem verbs, the imperfect is like so: capere (to capture or seize)
    capiēbam
    capiēbās
    capiēbat
    capiēbāmus
    capiēbātis
    capiēbant
Note that it is easiest to think of what the endings -ere and ire lack. The imperfect -bā- + the personal ending, which we can call the imperfect conjugation, must be prefixed by -iē-.
A few examples:
    amābam - I was loving (A-conjugation--1st)
    monēbātis - You were warning [object/personage] (of something negative) (Pl.) (2nd Conjugation)
    'vincēbāmus - We were defeating (3rd conjugation)
    capiēbant - They were catching (short I-conjugation--3rd conjugation)
    pellēbat - She/he/it was propelling (drive something (not a vehicle), propel something) (consonantic conjugation)
(Wiki-reading tips: See discussion. Some of the above may be unclear, however the clarifying '--' and '/' indicate verification. We may not know what the original author intended, but we know what conjugations the examples are.)

## Future I, Active

Future active is a tense which, unsurprisingly, refers to something which has not yet happened. The endings are fairly basic, and follow fairly regular rules - however, the future endings used in 1st and 2nd conjugation differ from the endings of 3rd, 3rd-iō, and 4th.
For example - "amō, amāre" (1st conjugation) would be
    Amābō - I will love
    Amābis - You will love
    Amābit - He/She/It will love
    Amaābimus - We will love
    Amābitis - Y'all will love
    Amābunt - They will love
NOTE: 1st person singular and 3rd person plural use -bō and -bunt, not -bi-.
NOTE: the B and the BIs - the distinguishing feature of future tense in Latin.
With "veniō, venīre" (4th conjugation), however, the endings are different. In future, this is what they look like:
    Veniam - I will come
    Veniēs - You will come
    Veniet - He/She/It will come
    Veniēmus - We will come
    Veniētis - Y'all will come
    Venient - They will come
[deleted paragraphs go here. deleted to maintain rigorous accuracy, which we will go back to striving for.)
To clarify: venīre, veniō.. we know it is 4th conjugation verb and if we look at its first person singular conjugation, we see that it is an -iō verb, because the conjugation of the first person singular is "venio". (an io category exists within 3rd and fourth conjugations and is a more general concept which we will briefly introduce here by using venire, venio as an example).
Let's first identify what we know.
We know it is 4th conjugation -io because it ends in īre, which tells us that it is 4th conjugation, and io because its first person singular ends in io (venio). Because it is -iō, we leave the -i- in. So, when we are asked (as all textbooks should phrase these new questions):
What are the steps to form the future 2nd person conjugation?
We say:
* It is better to know more than you need: check the infinitive nominative singular, we now know that it is 4th conjugation io.
* We now know that we can form the stem: the stem is veni and can then add a personal ending--leaving in the i. We leave in the i because it is io. Because it looks weird, we never leave the i in the future perfect.
What is the form for venīre, in the future tense, in the 2nd person?
The answer is veniēs.

## Future conjugation

Example: I will love:
    amābō
The table at the end of this page tries to summarize the future tense, with both sets of personal endings. As the warning notes, this summary may confu panda
As an aid to your understanding, this table only applies to the future tense. Do not assume the table is displaying a pattern that is somehow applicable to all of Latin.
(Wiki-reading-tip: This is why they are in the future section, and were not discussed before.)
The A- and the E- conjugation are (relatively) straight-forward. The others are more advanced, and as the warning notes, could confuse a first-time student. Commercial textbooks probably explain it better at this point, although laying their explanation in a table like the one below is well-advised. Leave items marked with a ? in until issues are resolved.
Take a look at the following table:
| A | E | long I (vincere/3rd conj.) | short I | Consonantic |
| amā-bo | monē-bo | vinc-am | capi-am | pell-am |
| ama-bis | mone-bis | vinc-es | capi-es | pell-es |
| ama-bit | mone-bit | vinc-et | capi-et | pell-et |
| ama-bimus | mone-bimus | vinc-emus | capi-emus | pell-emus |
| ama-bitis | mone-bitis | vinc-etis | capi-etis | pell-etis |
| ama-bunt | mone-bunt | vinc-ent | capi-ent | pell-ent |
The vocabulary mostly consists of verbs, and can easily be looked up in a dictionary. We will give a limited translation below, and the rest, for those who are particularly adept at language learning, can be learned through immersion.
    capere (3rd conjugation--short ere): to seize, metaphorically or literally [see dictionary for full explanation]
    amare (first conjugation -are): to love
