Whidder

Part of speech: verb, noun

Definitions

1. Moving swiftly and noisily, as a bird or object does when it rushes past with a rapid whirring sound
2. To dart or hurry along quickly, usually accompanied by a faint buzzing or whirring noise
3. Describing rapid motion through the air with a fluttering, whizzing quality that makes a sound as it goes

Etymology: Whidder is rare, and its exact origin is uncertain. It most likely imitates the sound it describes, a rushing, whirring noise like wind or wings passing close by. That sound-based pattern is shared by "whizz" and "whirr," which have similar meanings. A resemblance to "whither," which in older English could mean to move quickly, has been suggested, but no firm link is established. Without a reliable documented history, the imitative explanation remains the most plausible account.
