Present Tense - Regular -ir Verbs
Let's consider the present tense of a regular "ir" verb. The verb meaning (to write) in Spanish is (escribir).
Now we take off the -ir ending:
escribir - ir = escrib
Now we add on one of the present tense endings: o, es, e, imos, ís, en (The ending chosen will depend upon the gender of the subject and whether it is singular or plural.)
escrib + (ending) --> escribo, escribes, escribe, escribimos, escribís, escriben
The different forms of the verb escribir are shown in the table below.
| yo |  escribo |
(I write) | |
| tú | escribes |
(you write) | |
| Ud./él/ella | escribe |
(you/he/she writes) | |
| nosotros (as) | escribimos |
(we write) | |
| vosotros (as) | escribís |
(you write) | |
| Uds./ellos/ellas | escriben |
(they write) |
There are many verbs that follow the same pattern. Some of the more common ones are listed as follows:
abrir - to open
asistir - to attend

escribir - to write
recibir - to receive
For regular Spanish verbs the ending is identical and you can simply follow a specific rule to determine the form for them all. See the table below.
