Did you know?

Hush your puppies and calm your kitties, it’s time to make much (tranquil) ado about quiescent. As you might expect from both its meaning and the sequence of its first four letters, quiescent shares roots with the far more common, and less formal, word quiet. In fact, short is the list of English words beginning "q-u-i-e" that have no kinship with quiet and its various relations suggestive of restfulness and calm. (Our unabridged dictionary lists only two: quiebracha and quiebrahacha, both rare variants of quebracho.) Today’s adjective quiescent traces back to the Latin verb quiēscere, meaning "to become quiet" or "to rest," and was possibly first used by Francis Bacon, who wrote in 1605 that "… as Aristotle endeavoureth to prove, that in all motion there is some point quiescent…" Way to bring it home, Bacon.
