1. G is the seventh letter of the English alphabet, and a vocal consonant. It has two sounds; one simple, as in gave, go, gull; the other compound (like that of j), as in gem, gin, dingy. See Guide to Pronunciation, §§ 231-6, 155, 176, 178, 179, 196, 211, 246.
Note: The form of G is from the Latin, in the alphabet which it first appeared as a modified form of C. The name is also from the Latin, and probably comes to us through the French. Etymologically it is most closely related to a c hard, k y, and w; as in corn, grain, kernel; kin L. genus, Gr. ░; E. garden, yard; drag, draw; also to ch and h; as in get, prehensile; guest, host (an army); gall, choler; gust, choose. See C.
2. Mus. G is the name of the fifth tone of the natural or model scale; -- called also sol by the Italians and French. It was also originally used as the treble clef, and has gradually changed into the character represented in the margin. See Clef. G♯ (G sharp) is a tone intermediate between G and A.
