Etymology

Origin of cinch¹

An Americanism first recorded in 1855–60; from Spanish cincha, from Latin cingula “girth,” from cing(ere) “to gird” + -ula -ule

Origin of cinch²

First recorded in 1885–90; perhaps from Spanish cinco “five,” also the name of a card game, from Vulgar Latin cinque (unrecorded), from Latin quinque; see also five ( def. )

Explanation

Something that's a cinch is incredibly easy. It's a cinch to eat a meticulously decorated cake — it's much more complicated to bake and frost one. Cinch is one of those words with many meanings that seem unrelated at first glance. The original 19th-century North American definition, which is still used today, is "saddle girth," the straps that keep a horse's saddle in place. As a verb, cinch means "to pull tight," the way you'd cinch a belt. Informally, to cinch is to make absolutely certain: "It'll cinch her college decision if that school offers a scholarship."
