swoop

v.

1560s, "to move or walk in a stately manner," apparently from a dialectal survival of Old English swapan "to sweep, brandish, dash," from Proto-Germanic *swaipanan, from PIE root *swei- "to swing, bend, to turn." Meaning "pounce upon with a sweeping movement" first recorded 1630s. Spelling with -oo- may have been influenced by Scottish and northern England dialectal soop "to sweep," from Old Norse sopa "to sweep." Related: Swooped; swooping.
