This guide will walk you through the definition, usage, and practical examples of verb infinitives in Spanish.

What is a Spanish Verb Infinitive?

A verb infinitive in Spanish is the base form of a verb, ending in -ar, -er, or -ir. It does not change based on the subject or tense. For example, the verb 'hablar' (to speak) is an infinitive. You won't find it conjugated to indicate who is speaking or when the action occurs.

Unconjugated: Infinitives do not change form based on the subject (yo, tú, él, etc.) or tense (present, past, future).
Base Form: They serve as the base for all conjugated forms.
Endings: They always end in -ar, -er, or -ir.

Understanding Verb Endings: -AR, -ER, and -IR

Spanish verbs are categorized based on their infinitive endings: -ar, -er, and -ir. Each category has its own conjugation patterns.

-AR Verbs

-AR verbs are the most common and include words like 'hablar' (to speak), 'cantar' (to sing), and 'bailar' (to dance).

-ER Verbs

-ER verbs include words like 'comer' (to eat), 'beber' (to drink), and 'correr' (to run).

-IR Verbs
