cherub
n.
late 14c. as an order of angels, from Late Latin cherub, from Greek cheroub, from Hebrew kerubh (plural kerubhim) "winged angel," perhaps related to Akkadian karubu "to bless," karibu "one who blesses," an epithet of the bull-colossus. Old English had cerubin, from the Greek plural.
The cherubim, a common feature of ancient Near Eastern mythology, are not to be confused with the round-cheeked darlings of Renaissance iconography. The root of the terms either means "hybrid" or, by an inversion of consonants, "mount," "steed," and they are winged beasts, probably of awesome aspect, on which the sky god of the old Canaanite myths and of the poetry of Psalms goes riding through the air.
