The brake or bracken, the maidenhair, and the polypody are all well known ferns. Christmas fern. See Christmas. <botany> Climbing fern The European goatsucker. The short-eared owl. Fern shaw, a fern thicket. Origin: AS. Fearn; akin to D. Varen, G. Farn, farnkraut; cf. Skr. Parna wing, feather, leaf, sort of plant, or Lith. Papartis fern.

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." Source: Websters Dictionary (01 Mar 1998) |
