Etymology

Origin of bat¹

First recorded in 1175–1225; Middle English noun bat, bot, batte, Old English batt, perhaps from Celtic; compare Irish, Scots Gaelic bat, bata “staff, cudgel”; Middle English verb batten, partly from the noun, partly from Old French batre; see batter ¹

Origin of bat²

First recorded in 1570–75; apparently from Scandinavian; compare dialectal Swedish natt-batta, variant of Old Swedish natt-bakka “night-bat”; replacing Middle English bakke, bak (from Scandinavian), Middle English balke for unrecorded blake, from Scandinavian; compare dialectal Swedish natt-blacka, Old Icelandic ledhr-blaka “bat,” equivalent to ledhr “skin, leather” + blaka “flutter”

Origin of bat³

An Americanism dating back to 1835–40, extended sense of earlier “flutter like a hawk” first recorded in 1605–15; variant of see origin at bate ²

Explanation

A bat is used in the sports of baseball and cricket to hit a small, hard ball. In baseball, a bat can be made out of wood or aluminum. Bat can be a verb as well: when you're up at bat in a baseball game, it means it's your turn to bat with the bat. There is also an animal called a bat, a small, nocturnal bird-like mammal. People can be said to "bat their eyelashes," or flutter them flirtatiously, as well. This last meaning, from the mid-1800s, comes from an earlier sense of bat, "flutter like a hawk's wings."
