she-male (n.)

"the female person referred to," third person nominative fem. pronoun, used as a substitute for the name of a female or anything regarded as female, mid-12c., probably evolving from Old English seo, sio (accusative sie), fem. of the demonstrative pronoun (masc. se) "the," from PIE root *so- "this, that" (see the).

The Old English word for "she" was heo, hio, however by 13c. the pronunciation of this had converged by phonetic evolution with he "he," which apparently led to the fem. demonstrative pronoun being used in place of the pronoun (compare similar development in Dutch zij, German sie, Greek he, etc.).

The original h- survives in her. A relic of the Old English pronoun is in Manchester-area dialectal oo "she." As a noun meaning "a female human being, a woman," she is attested from early 14c. Also used to signify "female" with the names of other creatures (late 14c.; she-wolf, etc.). The attempted gender-neutral pronoun form s/he is attested by 1977.

late 14c., "male human being; male fish or land animal; one of the sex that begets young," from Old French masle (adj.) "masculine, male, adult," also used as a noun (12c., Modern French mâle), from Latin masculus "masculine, male, worthy of a man" (source also of Provençal mascle, Spanish macho, Italian maschio), diminutive of mas (genitive maris) "male person or animal, male."

Male, matching female, applies to the whole sex among human beings and gender among animals, to the apparel of that sex, and, by figure, to certain things, as plants, rimes, cesuras, screws, joints. Masculine, matching feminine, applies to men and their attributes and to the first grammatical gender; a woman may wear male apparel and have a masculine walk, voice, manner, temperament.
