I didn't know this and now I do, so I wanted to share what I found. For example, the words "male" and "female" are not etymologically related (check below). another thing I didn't know is that ladies were originally loaf kneaders.
Etymologies:
WOMAN: Old English wīfmann, from wīf (‘adult female’, Modern English wife) + mann (‘human being’).
MALE: Middle English male, borrowed from Old French masle, malle (Modern French mâle), from Latin masculus (“‘masculine, a male’”), diminutive of mās (“‘male, masculine’”).
FEMALE: From Old French femelle, from Mediaeval Latin femella (“‘a female’”), from Latin femella (“‘a young female, a girl’”), diminutive of femina (“‘a woman’”). The ending was remodelled under the influence of "male", to which "female" is not etymologically related.
LADY: From Middle English lavedi, from Old English hlǣfdīġe, originally literally ‘loaf-kneader’
LASS: From Middle English lasse < Old Norse *lasqa (“‘an unmarried woman’”). Cognate with Scots lassie.
