More about vibrissa
Vibrissa, 鈥渙ne of the stiff hairs growing about the mouth of an animal, such as a cat鈥檚 whisker,鈥� is restricted pretty much to (human) anatomy, ornithology, and zoology. Vibrissa is the singular of the Late Latin plural noun vibrissae, a word that occurs only once, in a work by Sextus Pompeius Festus, a Roman grammarian and lexicographer who flourished in the late 2nd century a.d. Festus defines vibrissae as 鈥渢he nose hairs of a human being, so called because when they are pulled out, the head shakes (caput 惫颈产谤腻迟耻谤)鈥� (vibrissae does in fact derive from the Latin verb 惫颈产谤腻谤别 鈥渢o shake鈥�). This 鈥渉uman鈥� sense is the original meaning in English in the late 17th century, but it is no longer common; the more general zoological and ornithological meaning arose in the first half of the 19th century. The singular form vibrissa first appears in English in the first quarter of the 19th century.
