Etymology

Origin of section

First recorded in 1550–60; from Latin sectiōn- (stem of sectiō ) “a cutting,” equivalent to sect(us) (past participle of secāre “to cut”; see saw ¹) + -iōn- -ion

---

Explanation

A section is a part or piece of something that fits together with the other pieces to make a whole. Like the arts section of a newspaper, or the rhythm section of the band that gets reviewed in it. The root of section is the Latin word sect, which means "cut." Think dissect ("cut into pieces"), or bisect ("cut in two"). Insects are called insects because they're made up of sections — the head, the abdomen, and the thorax. It almost looks like they've been carved into three separate parts.
