In Latin, ipse dīxit means “he himself said.” The feminine equivalent, “she herself said,” is ipsa dīxit. The plural versions, both meaning “they themselves said,” are ipsī dīxērunt for a group of men or a mixed-gender group and ipsae dīxērunt for a group of women. Ipse dixit was first recorded in English in the late 15th century.

Uncia, meanwhile, is the source of both inch and ounce. Quincunx was first recorded in English in the 1640s.
