De rigueur

The loanword de rigueur, meaning socially obligatory, proper, or required by custom, functions as an adjective in English. It comes from French, where it means, literally, of rigor and, less literally, according to strictness. De rigueur is also a common expression in that language, where it means roughly the same as in English.

De rigueur has been in English a few centuries, so it does not have to be italicized in normal use (we italicize it here because it is presented out of context). But many publications italicize it anyway.

In English, the phrase is usually pronounced duh ri-GUR—with the accent on the last syllable.
