Some Spanish verbs are perfectly regular in every present-tense form **except the yo form**, which takes an unexpected ending so the word "sounds right." These are called *irregular yo verbs*.
|
|
|
|
## Key Rules
|
|
- The yo form is irregular; **all other present-tense forms follow the normal -ar / -er / -ir pattern.**
|
|
- Common irregular yo endings:
|
|
- **-go**: salir → salgo, hacer → hago, tener → tengo, poner → pongo, suponer → supongo, traer → traigo (with -i-).
|
|
- **-zco**: verbs ending in *-cir* and *-cer* after a vowel: conducir → conduzco, traducir → traduzco, conocer → conozco, parecer → parezco.
|
|
- **-oy**: dar → doy, ser → soy, estar → estoy, ir → voy.
|
|
- **-eo**: ver → veo.
|
|
- **-jo**: proteger → protejo (this is the only verb of its kind; it is actually a spelling change so g sounds like /x/ before -o).
|
|
- Some "irregular yo" verbs are **also stem-changing** in other forms (e.g., **tener**: *tengo, tienes, tiene, tenemos, tenéis, tienen*).

## Notes & Gotchas
|
|
- The **-go** ending is by far the most common irregular-yo pattern.
|
|
- For **-cer / -cir** verbs preceded by a vowel, the yo form takes **-zco**, not just **-co** (avoids the awkward *traduco*, *conoco*).
|
|
- Some of these verbs combine an irregular yo with stem changes (e.g., **tener → tengo / tienes**, **decir → digo / dices**).
|
|
- **Proteger** is unique: the *g* is preserved as **j** in *protejo* so the consonant stays soft (Spanish *g* before *o/a* would otherwise become a hard /g/).
|
|
- Don't confuse **traigo** (I bring, from *traer*) with **trago** (I swallow, from *tragar*) — that vowel matters.
