Kay
Kay f, m
English:
1 (
f.) Pet form of any of the various female names beginning with the letter
K- (cf.
DEE (SEE
Dee) and
JAY (SEE
Jay)), most notably
KATHERINE (SEE
Katherine) and its variants.
2 (
m.) Comparatively rare male name, which presumably originated in honour of the Arthurian knight so called, although Sir Kay is not a particularly attractive character. His name seems to be a Celticized form of
Latin Gaius, an old Roman given name of uncertain derivation (cf.
CAYO (SEE
Cayo)).
