Etymology

Origin of faction¹

First recorded in 1500–10; < Latin factiōn- (stem of factiō ) “a doing, company, division,” equivalent to fact(us) “done, made” ( fact ) + -iōn- -ion

Origin of faction²

1965–70; blend of fact and fiction

Explanation

Fractions are smaller parts of whole numbers: one-quarter, one-tenth, one-half, and a faction is a smaller portion of a larger group that breaks away from it. A faction might take a fraction of the people from a large group and start a new group. The Latin source of the word faction means to "do" or "make," though a faction can seem to be a taking away or un-doing. Politics is one area where faction gets a lot of use, because a political party often starts with a large group but has some members who disagree with a belief or direction. These members separate from the larger party and become a faction of their own, with many of the same beliefs as the original group but with a few new differences, too.
