Did You Know?

If you took French in school, you might remember that liaison is the term 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 "bo zart." We can thank French for the origin of the term, as well. Liaison derives from the Middle French lier, meaning "to bind or tie," and is related to our word liable. Our various English senses of liaison apply it to all kinds of bonds-from people who work to connect different groups to the kind of relationship sometimes entered into by two people who are attracted to one another.
