Major is a rank of commissioned officer, with corresponding ranks existing in many military forces. It is also used in some police forces such as the New York State Police, New Jersey State Police and several others.

When used unhyphenated, in conjunction with no other indicator of rank, the term refers to the rank just senior to that of an army captain and just below the rank of lieutenant colonel. It is considered the most junior of the field ranks. In some militaries, notably France, the rank is referred to as commandant, while in others it is known as captain-major. It is also used in some police forces and other paramilitary rank structures.

When used in hyphenated or combined fashion, the term can also imply seniority at other levels of rank, including general-major or major general, denoting a mid-level general officer, and sergeant major, denoting the most senior NCO of a military unit.

It can also be used with a hyphen to denote the leader of a military band such as in pipe-major or drum-major.

A modern stadium (plural stadiums/stadia) is a place or venue for (mostly) outdoor sports, concerts, or other events and consists of a field or stage either partly or completely surrounded by a structure designed to allow spectators to stand or sit and view the event.)

Pausanias noted that for about half a century the only event at the ancient Greek Olympic festival was the race that comprised one length of the stade at Olympia, where the word "stadium" originated.

"Stadium" comes from the Greek word "stadion" (στάδιον), a measure of length equalling the length of 600 human feet. As feet are of variable length the exact length of a stadion depends on the exact length adopted for 1 foot at a given place and time. Although in modern terms 1 stadion = 600 ft (180 m), in a given historical context it may actually signify a length up to 15% larger or smaller.

A Roman stadium was defined somewhat differently to be a distance of 125 passus (double-paces), equal to about 185 m (607 ft).

Although most dictionaries provide for both "stadiums" and "stadia" as valid plurals, etymological sticklers sometimes apply "stadia" only to measures of length in excess of 1 stadium. (That the "stadium" measurement is used only in historical contexts perhaps explains the sustained use of the archaic plural.)

A soundtrack can be recorded music accompanying and synchronized to the images of a motion picture, book, television program or video game; a commercially released soundtrack album of music as featured in the soundtrack of a film or TV show; or the physical area of a film that contains the synchronized recorded sound.

In movie industry terminology usage, a sound track is an audio recording created or used in film production or post-production. Initially the dialogue, sound effects, and music in a film each has its own separate track (dialogue track, sound effects track, and music track), and these are mixed together to make what is called the composite track, which is heard in the film. A dubbing track is often later created when films are dubbed into another language. This is also known as a M & E track (music and effects) containing all sound elements minus dialogue which is then supplied by the foreign distributor in the native language of its territory.

The contraction soundtrack came into public consciousness with the advent of so-called "soundtrack albums" in the early 1950s. First conceived by movie companies as a promotional gimmick for new films, these commercially available recordings were labeled and advertised as "music from the original motion picture soundtrack." This phrase was soon shortened to just "original motion picture soundtrack." More accurately, such recordings are made from a film's music track, because they usually consist of the isolated music from a film, not the composite (sound) track with dialogue and sound effects.
