I checked the online dictionary and 'un bleu' appears to signify 'a person who is green, inexperienced'. But what is a natural French phrase to say 'I guess you're not green in this' in negative? Having the meaning that 'I guess you already have some experience in this'. I would like to say a thing like below but does this sound natural?
- 'Je suppose que tu n'es plus un bleu dans ce domaine'
- 'I guess you're not green in this, but when you're out there in the middle of the wild, be prepared for anything that might happen.'
