Where ser breaks the pattern
- soy, eres, es. The present of ser is irregular in every person.
- fui, fue. The preterite of ser is the same as the preterite of ir: fui, fue, fueron. The sentence tells you which verb it is. The imperfect subjunctive is built on it: fuera.
- era, eras, éramos. The imperfect is irregular, like the imperfect of ver and ir.
- sea. The present subjunctive has its own stem, se-.
- sé. The tú command is one syllable.
Vos and vosotros
| vos sos, sé | Argentina, Uruguay, Paraguay and much of Central America. The other tenses use the tú form. |
|---|---|
| vosotros sois, sed | Spain. Latin America says ustedes son. |
Same pattern
- ir fui, vaya
