Practice Exercises
Confusing ser and ir in past tense since forms are identical. Context is the only clue. 🇬🇧 English speakers: In English, 'was' and 'went' are clearly different. Having identical forms for both verbs is very confusing.

Ayer fui al cine.

Yesterday I went to the cinema.

Fui = I went (ir). Context: al cine = destination → this is IR, not ser.

La fiesta fue muy divertida.

The party was very fun.

Fue = was (ser). Context: describing a characteristic → this is SER, not ir.

Fuimos a la playa el domingo.

We went to the beach on Sunday.

Fuimos = we went (ir). 'A la playa' = destination → IR.
