5. c ·- c is the third letter of the english alphabet. it is from the latin letter c, which in old latin represented the sounds of k, and g (in go); its original value being the latter. in anglo-saxon words, or old english before the norman conquest, it always has the sound of k. the latin c was the same letter as the greek /, /, and came from the greek alphabet. the greeks got it from the ph/nicians. the english name of c is from the latin name ce, and was derived, probably, through the french. etymologically c is related to g, h, k, q, s (and other sibilant sounds). examples of these relations are in ·lat. acutus, ·eng. acute, ague; ·eng. acrid, eager, vinegar; ·lat. cornu, ·eng. horn; ·eng. cat, kitten; ·eng. coy, quiet; ·lat. circare, ·of cerchier, ·eng. search.
