Lever
Etymology

The word "lever" entered English around AD 1300 from Old French: levier. This sprang from the stem of the verb lever, meaning "to raise". The verb, in turn, goes back to Latin: levare, itself from the adjective levis, meaning "light" (as in "not heavy"). The word's primary origin is the Proto-Indo-European stem legwh-, meaning "light", "easy" or "nimble", among other things. The PIE stem also gave rise to the English word "light".
