Pronunciation: [da yeur]
Meaning: besides, moreover; for that matter; might I add, by the way
Literal translation: from elsewhere
Notes: The adverbial French expression d'ailleurs literally means "besides" or "moreover," but it also has two other uses:
- It can be used to add a bit of interesting but non-essential information, the way you might say "might I add" or "by the way."
- It's often tacked on to sentences with no real meaning - it's kind of a filler, like the English word "so."

D'ailleurs is the required contraction of the preposition de (of, from, about) plus the adverb ailleurs (elsewhere, somewhere else).
