   genre, fr. L. genus, generis, birth, descent, race, kind,
   gender, fr. the root of genere, gignere, to beget, in pass.,
   to be born, akin to E. kin. See {Kin}, and cf. {Generate},
   {Genre}, {Gentle}, {Genus}.]
   1. Kind; sort. [Obs.] ``One gender of herbs.'' --Shak.

      sex; and secondarily according to some fancied or imputed
      quality associated with sex.

            Gender is a grammatical distinction and applies to
            words only. Sex is natural distinction and applies

   Note: Adjectives and pronouns are said to vary in gender when
         the form is varied according to the gender of the words
         to which they refer.

gender
     n 1: a grammatical category in inflected languages governing the
          agreement between nouns and pronouns and adjectives; in
          some languages it is quite arbitrary but in
          Indo-European languages it is usually based on sex or
          animateness [syn: {grammatical gender}]
     2: the properties that distinguish organisms on the basis of
        their reproductive roles; "she didn't want to know the sex
        of the foetus" [syn: {sex}, {sexuality}]
