Did You Know?
The whiskers of a cat qualify as vibrissae (that’s the plural of vibrissa), as do the hairlike feathers around the bill of some birds - especially the insect-feeding kind. And when scientists first used vibrissa in the late 17th century, they used the word to refer specifically to the hairs inside the human nostril. Science got this word, as it has many others, from Latin. Vibrissa comes from vibrare, which means all of the following: "to brandish," "to wave," "to rock," and "to propel suddenly." Other vibrare descendents in English include vibrate, vibrato, and veer.
