Ser Present Practice

Ser (to be (essence)) in the present: 14 free exercises with an explanation after every answer, plus the full conjugation table.

IWhat to watch for

Ser is the most irregular verb in the Spanish present tense: soy, eres, es, somos, sois, son share almost nothing with the infinitive, so the six forms simply have to be memorized. You use them for identity, profession, origin, time, dates, events, and permanent descriptions.

The biggest trap is reaching for estar when the sentence describes what something IS rather than how it is right now — professions, nationalities, materials, and the time or place of an event all take ser.
