Tip

Working with the subjunctive

The subjunctive isn't a tense — it's a mood. It signals that the speaker views the action as uncertain, desired, or evaluated rather than asserted as fact. Triggers come in four families: WEIRDO (Wishes, Emotion, Impersonal expressions, Recommendations, Doubt, Ojalá) is the standard mnemonic. When you see "que" after one of these triggers, the verb that follows is almost always subjunctive. The irregular subjunctive stem comes from the yo form of the present indicative — learn "hago" and you know "haga" is the subjunctive stem.

Questions

Frequently asked questions

How do you conjugate comer in the present subjunctive?
The present subjunctive of comer is: yo coma, tú comas, él/ella/usted coma, nosotros/as comamos, vosotros/as comáis, ellos/ellas/ustedes coman. -er verbs swap their indicative 'e' endings for 'a' endings — every regular -er verb follows this pattern (beber → beba, leer → lea).
When do I need to use the subjunctive of comer?
Use it after triggers of doubt, emotion, will, or impersonal expressions: 'Quiero que comas algo' (I want you to eat something), 'Es importante que comamos juntos' (It's important we eat together), 'Dudo que coman pescado' (I doubt they eat fish). Negative commands also use the subjunctive: 'No comas tan rápido' (Don't eat so fast).
Why do -er and -ir verbs use 'a' in the subjunctive?
Spanish subjunctive endings flip the thematic vowel: -ar verbs (which use 'a' in the indicative) use 'e' in the subjunctive (hable); -er/-ir verbs (which use 'e/i' in the indicative) use 'a' in the subjunctive (coma, viva). This vowel-flip pattern was inherited from Latin and signals the mood shift across every conjugated form. The result: -er and -ir verbs share IDENTICAL subjunctive forms (coma/viva, comas/vivas, coma/viva, comamos/vivamos…).
