Etymology

Origin of mate¹

First recorded in 1350–1400; Middle English mate, maite “friend, companion, shipmate, mate (ship's officer), fellow creature,” from Middle Low German mate, gemate “messmate”, replacing Middle English mette, mete “table companion, messmate, partner,” Old English gemetta “messmate, guest”; see origin at meat

Origin of mate²

First recorded in 1175–1225; Middle English verb maten, matein, matten “to checkmate, defeat,” from Old French mater, ultimately from Persian; see origin at checkmate

Origin of mate³

First recorded in 1710–20; from American Spanish, from Quechua mati, the calabash gourd in which the herb is steeped

Explanation

Someone's mate is their spouse, partner, boyfriend, or girlfriend. Your grandmother's long-term sweetheart is her mate. Awwww. A husband or wife is one kind of mate, and animals have mates too, chosen for reproduction and sometimes to assist in raising babies. Anything that comes in a pair — like socks, contacts, shoes, or earrings — also has a mate. Your pal or buddy can be called a mate as well. As a verb, to mate means "to breed" or "to reproduce." In Middle Low German, mate means "one eating at the same table."
