That depends on context, of course. But let's say: Je ne parle pas bien le portugais, mais je me débrouille. I don't speak Portuguese well, but I can manage. ... but I can get along. ... but I can get by. ... but I can handle myself OK. ... but I can muddle through. ... but I can make myself understood. (very context specific, this one!)

En anglais, tu peux dire 'I manage ok'.

Merci pour ta réponse , j'ai trouvé "get by well" ca a la même signification?
