   Female rhymes (Pros.), double rhymes, or rhymes (called in French feminine rhymes because they end in e weak, or feminine) in which two syllables, an accented and an unaccented one, correspond at the end of each line.

   Note: A rhyme, in which the final syllables only agree (strain, complain) is called a male rhyme; one in which the two final syllables of each verse agree, the last being short (motion, ocean), is called female.
   --Brande & C.

   Syn: Female, Feminine.

   Usage: We apply female to the sex or individual, as opposed to male; also, to the distinctive belongings of women; as, female dress, female form, female character, etc.; feminine, to things appropriate to, or affected by, women; as, feminine studies, employments, accomplishments, etc. ``Female applies to sex rather than gender, and is a physiological rather than a grammatical term. Feminine applies to gender rather than sex, and is grammatical rather than physiological.''
   --Latham.
