Did you know?

If you took French in school, you might remember that liaison is the word for the phenomenon that causes a silent consonant at the end of one word to sound like it begins the next word when that word begins with a vowel, so that a phrase like beaux arts sounds like \boh zahr\. We can thank French for the origin of the term liaison, as well. It comes from Middle French lier, meaning “to bind or tie.” Other English senses of liaison apply it to all kinds of bonds—from binding and thickening agents used in cooking (as in “a butter and flour liaison”), to people who work to connect different groups, to the kind of secret relationship sometimes entered into by two people who are romantically attracted to one another.
