Word Origin and History for trap
n.

"contrivance for catching unawares," late Old English træppe "snare, trap," from Proto-Germanic *trap- (cf. Middle Dutch trappe "trap, snare"), related to Germanic words for "stair, step, tread" (cf. Middle Dutch, Middle Low German trappe, treppe, German Treppe "step, stair"). Probably akin to Old French trape, Spanish trampa "trap, pit, snare," but the exact relationship is uncertain. The connecting notion seems to be "that on which an animal steps." Sense of "deceitful practice, trickery" is first recorded c.1400. Sense in speed trap recorded from 1906. Slang meaning "mouth" is from 1776. Trap door "door in a floor or ceiling" (often hidden and leading to a passageway or secret place) is first attested late 14c.

v.

c.1400, "ensnare (an animal), catch in a trap; encircle; capture," from trap (n.) or from Old English betræppan. Figurative use is slightly earlier (late 14c.). Related: Trapped; trapping.

trap in Technology


1. A program interrupt, usually an interrupt caused by some exceptional situation in the user program. In most cases, the OS performs some action, then returns control to the program.
2. To cause a trap. "These instructions trap to the monitor." Also used transitively to indicate the cause of the trap. "The monitor traps all input/output instructions."
This term is associated with assembler programming ("interrupt" or "exception" is more common among HLL programmers) and appears to be fading into history among programmers as the role of assembler continues to shrink. However, it is still important to computer architects and systems hackers (see system, sense 1), who use it to distinguish deterministically repeatable exceptions from timing-dependent ones (such as I/O interrupts).
