Origins

Meanings 1–8

It comes from Middle English able, borrowed via Old Northern French able (a variant of Old French abile, habile), from Latin habilis ("easily managed or handled; apt; skillful"), formed from habeō ("to have, possess") plus the suffix -ilis. The native Old English verb for being able, magan, survives as may, which developed a different meaning.
