crank

A word that once meant simply “bent” ended up naming the kind of person who seems mentally bent, too. In Old English it was tied to weaving gear and twisting motion, the sort of everyday awkwardness you’d notice in a loom, a shaft, or a crooked bit of wood. By the 1500s, English had also borrowed a darker Continental sense: a counterfeit beggar pretending to be sick, which is a pretty brutal piece of street slang to hitch to such an old Germanic word. Then came the fun part: in 1833, English starts using crank for an eccentric obsessive, and you can almost hear the language shrug and say, “well, that mind is twisted.” The older adjective cranky meant “merry” or “lively” in some dialects, then slid toward irritability, so the word’s whole family keeps circling the same image of something bent, off-kilter, or not quite running straight. That’s the memory hook: a crank is what happens when a straight line takes a turn it was never meant to take.
