"contrivance for catching unawares," late Old English træppe, treppe "snare, trap," from Proto-Germanic *trep- (cognates: Middle Dutch trappe "trap, snare"), related to Germanic words for "stair, step, tread" (Middle Dutch, Middle Low German trappe, treppe, German Treppe "step, stair," English tread (v.)), and probably literally "that on or into which one steps," from PIE *dreb-, extended form of root *der- (1), an assumed base of words meaning "to run, walk, step." Probably akin to Old French trape, Spanish trampa "trap, pit, snare," but the exact relationship is uncertain.\n

\nSense of "deceitful practice, device or contrivance to betray one" is first recorded c.1400. Meaning "U-shaped section of a drain pipe" is from 1833. Slang meaning "mouth" is from 1776. Speed trap recorded from 1908. Trap door "door in a floor or ceiling" (often hidden and leading to a passageway or secret place) is first attested late 14c.

Overprinting

Comparison of a knock-out with and without trapping, and overprinting for perfect and imperfect registration.

Rows are as follows:
1. The cyan (lighter) plate,
2. The magenta (darker) plate,
3. Result with perfect registration (some monitors show slight misalignment), and
4. Result with imperfect registration.]] Trap on a press is the ability of a printed ink to accept the next printed ink compared to how well paper accepts that ink. Registration is when all printed images are lined up over one another. Trapping is a term originally used as a measure of how well one ink printed on top of another. With the advent of Pre-press Software the term was misused to describe the compensation for misregistration between printing units on a multicolor press that was traditionally known as "Chokes and Spreads". This misregistration causes unsightly gaps or white-space on the final printed work. Trapping involves creating overlaps (spreads) or underlaps (chokes) of objects during the print production process to eliminate misregistration on the press.

In computing and operating systems, a trap, also known as an exception or a fault, is typically a type of synchronous interrupt typically caused by an exceptional condition (e.g., breakpoint, division by zero, invalid memory access). A trap usually results in a switch to kernel mode, wherein the operating system performs some action before returning control to the originating process. A trap in a system process is more serious than a trap in a user process, and in some systems is fatal. In some usages, the term trap refers specifically to an interrupt intended to initiate a context switch to a monitor program or debugger.

In SNMP, a trap is a type of PDU used to report an alert or other asynchronous event about a managed subsystem.

Trap (1966) is the first novel by Australian author Peter Mathers. It won the Miles Franklin Award for 1966.

TRAP is an instruction command in the LC-3 (Little Computer 3) educational assembly language that consists of a set of basic service routines to simplify operations. Each service routine is created with a combination of other basic operations in the LC-3 instructions set. Although a user can reconstruct these service routines, the TRAP instruction is available for advanced users.

Trap is a sculpture by American artist Tony Smith which was made in an edition of nine with one artist's proof. This bronze sculpture was designed to be large-scale, but was only realized in bronze of the smaller size in 1968. The bronze was patinated to appear black.

In plumbing, a trap is a U-, S-, or J-shaped pipe located below or within a plumbing fixture. An S-shaped trap is also known as the S-bend invented by Alexander Cummings in 1775 but became known as the U-bend following the introduction of the U-shaped trap by Thomas Crapper in 1880. The new U-bend could not jam, so, unlike the S-bend, it did not need an overflow. The bend is used to prevent sewer gases from entering buildings. In refinery applications, it also prevents hydrocarbons and other dangerous gases from escaping outside through drains.

The most common of these traps in houses is referred to as a P-trap. It is the addition of a 90 degree fitting on the outlet side of a U-bend, thereby creating a P-like shape. It is also referred to as a sink trap because it is installed under most house sinks.

Because of its shape, the trap retains a small amount of water after the fixture's use. This water in the trap creates a seal that prevents sewer gas from passing from the drain pipes back into the occupied space of the building. Essentially all plumbing fixtures including sinks, bathtubs, and toilets must be equipped with either an internal or external trap.

Because it is a localized low-point in the plumbing, sink traps also tend to capture heavy objects (such as jewelry) that are inadvertently dropped into the sink. Traps also tend to collect hair, sand, and other debris and limit the ultimate size of objects that will pass on into the rest of the plumbing, thereby catching oversized objects. For all of these reasons, most traps can either be disassembled for cleaning or they provide some sort of cleanout feature.

When a large volume of water may be discharged through the trap, a standpipe may be required to prevent impact to other nearby traps.

"Trap" is a colloquial term for a secret compartment in an automobile. It can be intended to hide legal items, such as handguns or valuables, from thieves. But it can also be used to hide contraband, such as illegal drugs, from searches by authorities.

Until the 1980s, drugs trafficked in cars in the U.S. tended to be hidden in obvious places such as wheel wells or spare tires. In the early 1980s, the first magnetically or hydraulically actuated secret compartments, dubbed "urban traps" by the Drug Enforcement Administration, started to appear – often in door panels, dashboards, seats and roofs. By the early 1990s, however, police had learned to detect such traps by looking for suspicious buttons and switches. More recent traps have no visible controls, are electronically controlled and may require complicated procedures for access. For example, one trap found in the airbag compartment of a U.S. car in 2012 would only open if a driver was in the seat, all doors were closed (to prevent the trap from opening during a roadside police search), the defroster was turned on and a magnetic card was swiped over a sensor hidden in an air-conditioning vent.

The legality of traps is dependent on the jurisdiction in which they are used. In 2012, Alfred Anaya, famous among rich clients in California for his skill in installing sophisticated traps, was sentenced to more than 24 years in prison under U.S. federal law as a co-conspirator in a drug-trafficking operation. The conviction relied on testimony that Anaya had seen one of his clients stash some $800,000 in cash in a trap. The prosecution successfully argued that Anaya must have deduced from this that the trap was to be used for drug trafficking.
