Past Perfect

FORM = [had + past participle]

Examples:

·       You had eaten Mexican food before.

·       Had you eaten Mexican food before?

·       You had not eaten Mexican food before.

The Past Perfect expresses the idea that something occurred before another action in the past. It can also show that something happened before a specific time in the past.

With Non-Continuous Verbs and some non-continuous uses of Mixed Verbs, we use the Past Perfect to show that something started in the past and continued up until another action in the past.
