1911 Encyclopædia Britannica, Volume 7… (1911)
“ The word is derived from the French coqueter, which originally means, “to strut about like a cock-bird,” i.e. when it desires to attract the hens. The French substantive coquet, in the sense of “beau” or “lady-killer,” was formerly commonly used in English; but the feminine form, coquette, now practically alone survives, in the sense of a woman who gratifies her vanity by using her powers of attraction in a frivolous or inconstant fashion. Hence “to coquet,” the original and more correct form, has come frequently to be written “to coquette.” ”
