# 06. The Present Progressive

> Source: [video link](https://youtube.com/watch?v=YHDZSHCt1DE&t=1399s)

The Spanish present progressive expresses an action happening **right now** (English "I am ___ing"). It's built with conjugated **estar** + the **gerund** (gerundio) of the action verb. The verb estar gets full coverage in the next chapter — here we focus on building the gerund and using it.

## Key Rules
- Formula: **conjugated *estar* + gerund**.
- **-ar verbs** → drop *-ar*, add **-ando**: *hablar → hablando*.
- **-er / -ir verbs** → drop ending, add **-iendo**: *comer → comiendo*, *vivir → viviendo*.
- Spelling rule: you cannot have three vowels in a row. Verbs whose stem ends in a vowel switch the *i* of *-iendo* to *y*: *leer → leyendo* (NOT *leiendo*), *traer → trayendo*, *oír → oyendo*.
- Stem-changing **-ir** verbs change their stem in the gerund:
  - *o → u*: *dormir → durmiendo*, *morir → muriendo*.
  - *e → i*: *decir → diciendo*, *pedir → pidiendo*, *sentir → sintiendo*.
- Subject pronoun is optional, but estar must agree with whoever is doing the action.

|---------|------|
| yo | estoy |
| tú | estás |
| él / ella / usted | está |

## Notes & Gotchas
- Don't use the present progressive for habitual or future actions the way English does ("I'm working tomorrow"). Spanish reserves it for actions in progress at this moment.
- Avoid common learner errors: *leiendo* → correct is *leyendo*; *dormiendo* → correct is *durmiendo*; *deciendo* → correct is *diciendo*.
- The full rules of *estar* (uses, accents, conjugation traps) are in the next chapter.
