XV. OF THE LETTER O.
The vowel O has three different sounds, which are properly its own:—
1. The open, full, primal, or long o; as in no, note, opiate, opacity, Roman.
2. The close, curt, short, or stopped o; as in not, nor, torrid, dollar, fondle.
3. The slender or narrow o, like oo; as in prove, move, who, to, do, tomb.
O, in many words, sounds like close or curt u; as in love, shove, son, come, nothing, dost, attorney, gallon, dragon, comfit, comfort, coloration. One is pronounced wun; and once, wunce. In the termination on immediately after the accent, o is often sunk into a sound scarcely perceptible, like that of obscure e; as in mason, person, lesson.
