English tenses combine time (past, present, future) with aspect. The continuous aspect (be + -ing) presents an action as in progress, temporary or incomplete. The perfect aspect (have + participle) looks back from one point to an earlier one.
Perfect continuous combines both: an activity continuing up to a point, often explaining a result: She was exhausted because she had been working* all night. By June I will have been living here for ten years.*
Compare completed vs ongoing: I’ve read your report (finished) vs I’ve been reading your report (not necessarily finished). He’s painted the room (result) vs He’s been painting (activity, maybe paint on his clothes).
Repeated actions can take the continuous: I’ve been calling you all day! but a number of actions takes the simple: I’ve called you five times.
| Aspect | Focus | Example |
|---|---|---|
| simple | fact / whole action | I work here. |
| continuous | in progress / temporary | I’m working from home this week. |
| perfect | earlier action relevant later | I’ve worked here since 2019. |
| perfect continuous | duration up to a point | I’ve been working all morning. |
Examples
- By the time the ambulance arrived, he had been lying there for an hour.
