Etymology
It is formed from Latin com- (“with, together”) + māter (“mother”).[2][1][3]
Earliest recorded meaning
It first appears in the letters of Gregory the Great, who asks his correspondent not to let his monks make women their commatres, that is, godmothers bound to them through a baptism.[2][4][5]
Semantic evolution
The word belongs to the spiritual kinship created by baptism: it named the godmother in her relation to the child's parents or to the godfather, and the mother in her relation to the godfather.[6][7] The Liber historiae Francorum has the line domina mea regina commater tua est, “my lady the queen is your fellow godmother”.[7] A law collection, the Quadripartitus, forbids a man to marry his commater or a nun, and in 1102 a council forbade nuns to become godmothers.[8]
In medieval Britain it also meant a female companion or gossip.[8] Italian comare comes from the Late Latin word.[5]
