## Verb "ir"/ Verbo ir

The verb to go is an important verb in Portuguese. It's an irregular verb:
| Person | Portuguese | English |
| 1. s. | eu vou | I go |
| 2. s. | você vai | you go |
| 3. s. | ele/ela vai | he/she/it goes |
| 1. p. | nós vamos | we go |
| 2. p. | vocês vão | you all go |
| 3. p. | eles/elas vão | they go |
See some examples:
    Nós vamos para a escola. ("We go to the school.")
    Eles vão para a casa deles. ("They go to their house.")

## Compound future/Futuro composto

The verb "ir" can work as an auxiliary verb for the (near) future tense (just like "to be going to" in English). This structure is made using the "ir" plus the infinitive of an other verb.
See some examples:
    Nós vamos ser amigos. ("We are going to be friends.")
    Eles vão estar aqui? ("Are they going to be here?")
    Ele não vai estudar português, mas eu vou. ("He is not going to study Portuguese, but I am going to.")

## Present indicative of regular verbs/Presente do indicativo de verbos regulares

The conjugation form for each stem vowel in the present indicative tense is much alike. There is a table below with all three of them (stem vowels are highlighted):
| Tense | Person | 1st conjugation | 2nd conjugation | 3rd conjugation |

| Present indicative | você | –a | –e | –e |
| Present indicative | ele/ela | –a | –e | –e |
| Present indicative | nós | –amos | –emos | –imos |
| Present indicative | vocês | –am | –em | –em |
| Present indicative | eles/elas | –am | –em | –em |
| Infinitive | | –ar | –er | –ir |
Conjugation rules:
* the first person singular (eu) always take -o.
* the second person singular (você) takes the stem vowel (ir-verbs take -e instead).
* the third person singular (ele/ela) takes the stem vowel (ir-verbs take -e instead).
* the first person plural (nós) takes the stem vowel plus -mos.
* the second person plural (vocês) is equals to the third person singular (você) plus -m.
* the third person plural (eles/elas) is equals to the third person singular (ele/ela) plus -m.
There is a table with three examples below: "cantar" ("to sing"), "comer" ("to eat") and "partir" ("to leave").
