Frequently Asked Questions

Why is 'ser' and 'ir' the same in the past tense?

Historically, the two verbs merged their forms in the preterite tense. You can tell them apart by the context: if there is an 'a' (to) after it, it's usually 'ir' (e.g., 'fui a la tienda').

When should I use 'ser' instead of 'estar'?

Use 'ser' for permanent traits, identity, time, and origin. Use 'estar' for temporary states and physical locations.

Is 'ser' always irregular?

Yes, it is one of the most irregular verbs in Spanish across almost all tenses.
