Etymology

Origin of mother¹

First recorded before 900; Middle English mother, moder, Old English mōdor; cognate with Dutch moeder, German Mutter, Old Norse mōthir; akin to Armenian mayr, Greek mḗtēr, mā́tēr, Irish máthair, Latin māter, Latvian māte, Persian mâdar, Russian mat', Sanskrit mātar-

Origin of mother²

First recorded in 1450–1500; probably special use of mother ¹, but perhaps another word, akin to Dutch modder “dregs,” Middle Low German moder “swampy land”; see mud

Explanation

A mother is a female parent: mothers nurture and mother children. It's also a term for an elderly woman or mother superior. Your mother is the woman who gave birth to you: mothers are parents, the female equivalent of a father. Besides biological mothers, there are stepmothers and adopted mothers: they all do mothering, which means taking care of children (or, sometimes, being overprotective of children). Oddly enough, a mother is also slimy substance that forms during the fermentation of wine or cider. But in any case, mothers give and sustain life.
