en passant

In passing / while passing byBy the way — for slipping a comment into the conversation

En passant literally means 'in passing', and in conversation it works like 'by the way': it lets you slip a side comment, question or compliment into the flow without breaking it. Drop it at the start of a remark — 'en passant, j'adore tes chaussures' — and you sound instantly more natural.
