C2 · Tense System Review — Lesson

The English tense system — the full picture

English has 12 tense-aspect combinations + future forms. At C2 you choose between them not by formula but by communicative intent.

Simple

complete actions, states, habits, facts

Continuous

in progress, temporary, ongoing — emphasis on duration

Perfect

earlier action linked to a reference point — emphasis on result

Perfect continuous

duration up to a reference point — both completion and ongoing
