Le Passé Composé + depuis longtemps= not long / not for long

Question

Maybe I've not understood this bit of the lesson, but shouldn't this say '= not in a long time' instead of '= not for long'?

Answer

Hi Harriet - can you be more specific about which sentence or part of the lesson you mean?

Answer

Sorry, tried to put it as the question title but it was too long. It's the second to last note of the lesson: 'Le Passé Composé + depuis longtemps OR ne...plus + Le Présent + depuis longtemps = not long / not for long
-> It's over and done in the past'

Answer

Ah, yes, I see what you mean. Indeed, those cases correlate to "not for a long time". I'll get that clarified. Thanks!

Answer

That's okay- just wanted to make sure I'd understood it properly!
