# 03. Conjugating Verbs (Present)

> Source: [video link](https://youtube.com/watch?v=YHDZSHCt1DE&t=632s)

The "primary fundamental" of Spanish: how regular verbs end in **-ar / -er / -ir**, and the six person-conjugations you produce by dropping the infinitive ending and adding a person-specific ending. Walks through *hablar*, *comer*, and *vivir* as the canonical models.

## Key Rules
- A Spanish infinitive must end in **-ar**, **-er**, or **-ir** (English infinitives are marked by the preposition "to": to eat, to walk).
- Conjugation = drop the infinitive ending → add the person ending matching the subject pronoun.
- Spanish has **6** person endings per tense (vs. English's 2 in the present).
- *-er* and *-ir* share four of six endings (yo, tú, él, ellos), making the systems similar.
- Focus first on **yo / tú / él / ellos** — these dominate everyday speech. *Nosotros* and *vosotros* matter but are less frequent.

## Notes & Gotchas
- *Como* (I eat) is also the word for "like / as" (e.g., *como te dije ayer* — "as I told you yesterday"). Context disambiguates.
- The pattern only covers **regular** verbs. Many useful verbs (*ser, estar, ir, tener, pensar, gustar*) are irregular or stem-changing and are covered in their own chapters.
- Subject pronouns are often dropped because the verb ending already encodes the person.
