English is a very simple language when it comes to the past tense. Every verb in English (apart from “to be”) has only one simple past form, no matter what the subject is, so we would say, for example,
This is true for every verb (apart from “to be”) and every subject. A few examples:
The toy broke.
It arrived too late.
The verb “to be” is the only exception. It is “was” in the first and third person singular and “were” in all other cases:
You were there.
He/she/it was in the kitchen.
We were sure.
You were friends.
They were alone.
