Regular -er and -ir verbs share a single set of subjunctive endings, which makes them surprisingly easy to master. Because their indicative endings typically contain the vowel -e- or -i-, the subjunctive flips to -a-, the opposite vowel.
Formation
The procedure is the same as for -ar verbs:
- Start with the yo form of the present indicative.
- Drop the final -o.
- Add the endings: -a, -as, -a, -amos, -an.
Beginning with the yo form means that verbs with a go-type irregularity (like tengo, vengo, salgo) carry that irregularity into the entire subjunctive.
Endings for -er and -ir Verbs
| Subject | Ending |
|---|---|
| yo | -a |
| tú | -as |
| él / ella / usted | -a |
| nosotros | -amos |
| ellos / ellas / ustedes | -an |
A huge benefit of the subjunctive is that -er and -ir verbs no longer have different endings for nosotros (as they do in the indicative, where we say comemos but vivimos). In the subjunctive, both become -amos.

Watch the Yo-Stem
Many verbs look irregular in the subjunctive but actually follow the regular pattern once you start from the yo form of the indicative. Consider these:
- tener → tengo → tenga, tengas, tenga, tengamos, tengan
- salir → salgo → salga, salgas, salga, salgamos, salgan
- hacer → hago → haga, hagas, haga, hagamos, hagan
