U, V.

U, or u, the 20th letter and 5th vowel of our alpha- bet, is formed in the voice by a round configu- ration of the lips, and a greater extrusion of the under one than in forming the letter o, and the tongue is also more camouflaged. The sound is short in curf, muf, tun, tul; but is lengthened by a final e, as in tune, tube, &c. In some words it is rather acute than long; as in brute, flute, lute, &c. It is mostly long in polysyllables; as in union, curious, &c.; but in some words it is obscure, as in nature, venture, &c. This letter in the form of V or v, is properly a consonant, and as such is placed before all the vowels; as in vacant, venal, vibrate, &c. Though the letters v and u had always two sounds, they had only the form v till the beginning of the fourth century, when the other form was introduced, the in- convenience of expressing two different sounds by the same letter having been observed long before. In nu- merals V stands for five; and with a dash added at top, thus V, it signifies 5000.
