Word History

Etymology

Noun

borrowed from Middle French & Latin; Middle French faccion, borrowed from Latin factiōn-, factiō "act of making, social set, band, group, self-seeking political group," from facere "to make, bring about, place, classify" + -tiōn-, -tiō, suffix of verbal action — more at fact

Note: A doublet of faction is fashion entry 1, from the Gallo-Romance outcome of Latin factiō, which maintains only the meaning "act of making," sparsely attested outside of early Latin except in legal use.

Noun combining form

borrowed from Latin -factiōn-, -factiō (as in satisfactiōn-, satisfactiō satisfaction)
