Flap
The word Flap can refer to several things.
- Flapping is a repetitive up-and-down motion most commonly associated with a bird's wing.
- A flap (aircraft) is a hinged surface on the trailing edge of an airplane wing.
- Flap, in (archaic) computer science jargon, refers to the process for unmounting a magnetic tape. When the system operator commanded a tape drive to unmount a tape, it would rewind the medium and then, as the tape unwrapped from the take-up reel, it would go "flap-flap-flap" as the feed reel spun down.
- In phonetics and phonology, a flap consonant is a sound produced by brief contact between the tongue and the roof of the mouth.
