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."
