Literal translation
to have the way of it
Meaning
to have the knack, the know-how
Explanation
To have the knack, the right way of doing things. The word biais, borrowed by standard French with a narrower and slightly negative sense, a roundabout means, keeps in Provençal its broad, positive meaning, manner, way, kind. Saying of someone that he has le biais is a plain compliment, a possible source of misunderstanding between a Provençal speaker and an outsider to the language.
