Entries linking to femaleness
female n.
early 14c., from Old French femelle "woman, female" (12c.), from Medieval Latin femella "a female," from Latin femella "young female, girl," diminutive of femina "woman, a female" ("woman, female," literally "she who suckles," from PIE root *dhe(i)- "to suck").
WHEN the Himalayan peasant meets the he-bear in his pride,
He shouts to scare the monster, who will often turn aside.
But the she-bear thus accosted rends the peasant tooth and nail.
For the female of the species is more deadly than the male.
[Kipling]
The sense in Vulgar Latin was extended from young humans to female of other animals, then to females generally. Compare Latin masculus, also a diminutive (see masculine). The spelling altered late 14c. in erroneous imitation of male. In modern use usually an adjective (which is attested from early 14c.). In reference to implements with sockets and corresponding parts, from 1660s.
-ness
word-forming element denoting action, quality, or state, attached to an adjective or past participle to form an abstract noun, from Old English -nes(s), from Proto-Germanic *in-assu- (cognates: Old Saxon -nissi, Middle Dutch -nisse, Dutch -nis, Old High German -nissa, German -nis, Gothic -inassus), from *-in-, originally belonging to the noun stem, + *-assu-, abstract noun suffix, probably from the same root as Latin -tudo (see -tude).
feminine adj.
mid-14c., "of the female sex," from Old French femenin (12c.) "feminine, female; with feminine qualities, effeminate," from Latin femininus "feminine" (in the grammatical sense at first), from femina "woman, female," literally "she who suckles" (from PIE root *dhe(i)- "to suck"). The usual modern sense of "woman-like, proper to or characteristic of women" is recorded from mid-15c. Related: Femininely.
The interplay of meanings now represented roughly in female "characteristic of the sex that bears children," feminine "having qualities considered appropriate to a woman," and effeminate "having female qualities in a bad sense, unmanly," and the attempt to keep them clear of each other, has led to many coinages. Among nouns, in addition to feminity "womanishness," femininity, femaleness, feminineness (1810, "female qualities"), there is feminitude (1878); feminility "womanliness" (1824); feminie "womankind" (late 14c.); femality (17c., "effeminacy;" 1754 "female nature"); feminacy "female nature" (1829); feminicity "quality or condition of being a woman" (1843). Also feminality (1640s, "quality or state of being female"), from rare adjective feminal "female, belonging to a woman" (late 14c.), from Old French feminal. And femineity "quality or state of being feminine," also "effeminate; womanly," from Latin femineus "of a woman, pertaining to a woman." feminile "feminine" (1640s) seems not to have survived.
