G. The letter G is of Italic origin, and was produced by a differentiation of C, to denote the original sound of that letter, as distinct from its other value of k. Of the two sounds of g, the hard and the soft, the former is the original one, which belonged to it in Latin, and persists, even before e and i (cf. get, give) in words of Anglo-Saxon origin, excepting before e final (cf. cringe). The name "guttural mute" is incorrect, since the throat plays no part in the formation of the sound. It was introduced into Latin about the sixth century A.D., and in English is chiefly confined to words of Romance origin.

“Are you dejected? here is comfort. Are you sinful? here is righteousness. Are you led away with present enjoyments? here you have honours, and pleasures, and all in Christ Jesus. You have a right to common pleasures that others have, and besides them you have interest in others that are everlasting, that shall never fail; so that there is nothing that is dejecting and abasing in man, but there is comfort for it in Christ Jesus.”
–Richard Sibbes, Description of Christ
