late 14c., "loop of cloth, rope, leather, etc.," probably of Celtic origin (compare Gaelic lub "bend," Irish lubiam), influenced by or blended with Old Norse hlaup "a leap, run" (see leap (v.)). In reference to magnetic recording tape or film, first recorded 1931. Computer programming sense first attested 1947.

"to form a loop," c.1400, "draw (a leash through a ring)," from loop (n.). Related: Looped; looping. Slang looped "drunk" is from 1934. Loop the loop (1900) originally was in reference to roller-coasters at amusement parks.\n\n"Loop-the-Loop" is the name of a new entertainment which goes further in the way of tempting Providence than anything yet invented. The "Loop" is an immense circle of track in the air. A car on a mimic railway shoots down a very steep incline, and is impelled around the inner side of this loop. ... The authorities at Coney Island are said to have prohibited "looping-the-loop" because women break their corset strings in their efforts to catch their breath as they sweep down the incline, and moreover, a young man is reported to have ruptured a blood vessel in his liver.

Loop or LOOP may refer to:

In electroacoustic music, a loop is a repeating section of sound material. Short sections of material can be repeated to create ostinato patterns. A loop can be created using a wide range of music technologies including digital samplers, synthesizers, sequencers, drum machines, tape machines, delay units, or they can be programmed using computer music software.

In reference to knots, loop may refer to:

• One of the fundamental structures used to tie knots. Specifically, it is a U-form narrower than a bight.
• A type of knot used to create a closed circle in a line.

Loop are an English alternative rock band, formed in 1986 in Croydon, Surrey.

The band went through several lineup changes, with frontman Robert Hampson being the only permanent band member. They split in 1991 following the release of their final album, A Gilded Eternity (1990). The 1989–90 lineup of Hampson, John Wills, Scott Dawson and Neil Mackay reforming in 2013 for a series of gigs. In November 2014, Hampson unveiled a new lineup of the band with himself as the sole original band member.

is the third in the series of Ring novels by Koji Suzuki.

The story revolves around a simulated reality, exactly the same as our own, known as the Loop: created to simulate the emergence and evolution of life. It is in this alternate universe that the events of the previous novels, Ring and Spiral took place.

A loop in mathematics, in a topological space X is a continuous function f from the unit interval I = [0,1] to X such that f(0) = f(1). In other words, it is a path whose initial point is equal to the terminal point.

A loop may also be seen as a continuous map f from the pointed unit circle S into X, because S may be regarded as a quotient of I under the identification of 0 with 1.

The set of all loops in X forms a space called the loop space of X.

In graph theory, a loop (also called a self-loop or a "buckle") is an edge that connects a vertex to itself. A simple graph contains no loops.

Depending on the context, a graph or a multigraph may be defined so as to either allow or disallow the presence of loops (often in concert with allowing or disallowing multiple edges between the same vertices):

• Where graphs are defined so as to allow loops and multiple edges, a graph without loops or multiple edges is often distinguished from other graphs by calling it a "simple graph".
• Where graphs are defined so as to disallow loops and multiple edges, a graph that does have loops or multiple edges is often distinguished from the graphs that satisfy these constraints by calling it a "multigraph" or " pseudograph".

Looping, in education, refers to the practice of a teacher remaining with the same group of students for more than one school year. For example, a teacher who teaches a third grade class and then goes on to teach the same students, the following year, for the fourth grade.

This is distinct from the teacher of a multi-age class, who teaches a specific range of school grades together. In this case, although each child remains with the same teacher for multiple years, the group of students being taught changes annually as older children leave the group and are replaced by younger students entering.

Looping is usual in Waldorf education, where the traditional goal has been for a primary teacher to remain as the lead teacher of a class for eight consecutive years, though in conjunction with numerous specialized teachers; in recent decades, many schools have been reducing the loop to a shorter interval.

The Loop is a beltway around Texarkana, a twin city in the U.S. states of Arkansas and Texas, running about 16 miles (26 km). Consisting a section of Interstate 49 in Arkansas, and Loop 151 and a section of I-369 and U.S. Highway 59 in Texas, it forms a three-quarter loop around the east, south and west sides of the city. ( Interstate 30 completes the circle on the north side.) The Loop is built to Interstate Freeway Standards.

The south side is bisected by State Line Avenue, which runs north–south along the state line. The whole half in Arkansas is Highway 151; US 59 intersects the Loop near the southwest corner, and so only the south side in Texas is Loop 151. Old US 59 into Texarkana (Lake Drive) is now State Highway 93.

Loop is the fifth album by Keller Williams, released in 2001. It features live recordings from three shows in the Pacific Northwest in 2000.

Loop is a 1997 British romantic comedy feature film produced by Tedi De Toledo and Michael Riley. It was written by Tim Pears and is the debut film of director Allan Niblo.

The writer of Loop, Tim Pears, also wrote the novel for In a Land of Plenty which was turned into an acclaimed 10 part TV drama serial for the BBC and produced by the London-based production company Sterling Pictures and Talkback Productions.

The Loop was a daily passenger train operated by Amtrak between Chicago and Springfield, Illinois. The Loop began on April 27, 1986, with funding support from the state of Illinois. The train acted as a counterpart to the State House, departing Chicago in the morning and returning in the afternoon. Funding shortfalls eliminated Saturday service in mid-1995, and the train ended altogether on June 28, 1996, after Illinois withdrew its support.

The Loop originally operated with refurbished bilevel cars from the Chicago & North Western Railway, but by 1987 Amtrak substituted Amfleet coaches, later supplemented by Horizon Fleet coaches.

The old inlet ran between the present villages of Ahrenshoop and Althagen. The Loop was roughly two metres deep and had posts for mooring boats and barges. Its navigability was frequently curtailed by storms and silting up. Today only a small ditch remains on the former Mecklenburg-Pomeranian border, which runs alongside a main road, the so-called Grenzweg ("border way").

The cartographer and court astronomer at the Mecklenburg court, Tilemann Stella, described the Loop thus: ''"Between the village of Oldenhagen [Althagen] and the Arnshope [Ahrenshoop], the waters of the Ribnitz river and lake break through into the salty sea. Beyond the beach is a large pile of rock and bricks at the place by the beach; that was the customs post, located 3 or 4 ruthen [50 metres] into the salty sea. Beyond that, forty or fifty posts stood in the salt sea, at the end of which was a large pile of rocks on which the fort stood."''

At the end of the 14th century the Pomeranian duke, Barnim VI, wanted to turn Ahrenshoop into a larger trading town in order to benefit from the growth in trade. The then Arneshop was an important trading post with up to 500 inhabitants. To that end, he had the place protected by ditches, border fortifications, customs posts and a fortified redoubt. Its further development failed, however, due to the vulnerability of the Loop to the vagaries of the weather.

The Victual Brothers also used the Loop and the Permin near Wustrow to enter the waters of the bodden, which they used as a refuge between their piratic raids. The Hanseatic city of Rostock, which envisaged its trading privileges being affected by a harbour on the Darß, finally had Ahrenshoop destroyed, after two failed attempts, in 1395 and the Darß Canal filled in.

LOOP is a programming language designed by Uwe Schöning, along with GOTO and WHILE. The only operations supported in the language are assignment, addition and looping.

The key property of the LOOP language is that the functions it can compute are exactly the primitive recursive functions.

Loop is a 1999 Venezuelan drama film directed by Julio Sosa Pietri. The film was selected as the Venezuelan entry for the Best Foreign Language Film at the 71st Academy Awards, but was not accepted as a nominee.
