Key Concepts & Vocabulary

Infinitivo (Infinitive)The original, unchanged form of a verb. In Spanish, these verbs end in -ar, -er, or -ir.vivir (to live), escribir (to write), abrir (to open)
Raíz (Stem)The part of the verb that is left after you take off the -ir ending. The stem usually doesn't change.For the verb 'vivir', the stem is 'viv-'.

Grammar Rules & Patterns
The -IR Verb Conjugation Pattern
1. Drop the -ir from the infinitive. 2. Add the new ending that matches the pronoun: yo (-o), tú (-es), él/ella/usted (-e), nosotros/nosotras (-imos), ellos/ellas/ustedes (-en).
Use this two-step pattern for any regular -IR verb to say who is doing the action right now.
The Special 'Nosotros' Rule
The ending for 'nosotros' is -imos. The vowel 'i' in the ending matches the vowel in the infinitive '-ir'.
This is an important difference from -AR verbs, which use '-amos'. For 'vivir', we say 'nosotros vivimos'. For 'hablar', we say 'nosotros hablamos'.
