"cloth ensign," late 15c., now in all modern Germanic languages (German Flagge, Dutch vlag, Danish flag, Swedish flagg, etc.) but apparently first recorded in English, of unknown origin, but likely connected to flag (v.1) or else an independent imitative formation "expressing the notion of something flapping in the wind" [OED]. A guess considered less likely is that it is from flag (n.2) on the notion of being square and flat.\n

\nMeaning "name and editorial information on a newspaper" is by 1956. U.S. Flag Day (1894) is in reference to the adopting of the Stars and Stripes by the Continental Congress on June 14, 1777.

1540s, "flap about loosely," probably a later variant of Middle English flakken, flacken "to flap, flutter" (late 14c.), which probably is from Old Norse flaka "to flicker, flutter, hang losse," perhaps imitative of something flapping lazily in the wind. Sense of "go limp, droop, become languid" is first recorded 1610s. Related: Flagged; flagging.

"flat stone for paving," c.1600, ultimately from Old Norse flaga "stone slab," from Proto-Germanic *flago- (see flake (n.)). Earlier in English as "piece cut from turf or sod" (mid-15c.), from Old Norse flag "spot where a piece of turf has been cut out," from flaga.

plant growing in moist places, late 14c., "reed, rush," perhaps from Scandinavian (compare Danish flæg "yellow iris") or from Dutch flag; perhaps ultimately connected to flag (v.1) on notion of "fluttering in the breeze."

1875, "place a flag on or over," from flag (n.1). Meaning "designate as someone who will not be served more liquor," by 1980s, probably from use of flags to signal trains, etc., to halt, which led to a verb meaning "inform by means of signal flags" (1856, American English). Meaning "to mark so as to be easily found" is from 1934 (originally by means of paper tabs on files). Related: Flagged; flagging.

A flag is a piece of fabric (most often rectangular or quadrilateral) with a distinctive design that is used as a symbol, as a signaling device, or as decoration. The term flag is also used to refer to the graphic design employed, and flags have since evolved into a general tool for rudimentary signalling and identification, especially in environments where communication is similarly challenging (such as the maritime environment where semaphore is used). National flags are potent patriotic symbols with varied wide-ranging interpretations, often including strong military associations due to their original and ongoing military uses. Flags are also used in messaging, advertising, or for other decorative purposes. The study of flags is known as vexillology, from the Latin word vexillum, meaning flag or banner.

Due to the use of flags by military units, 'flag' is also used as the name of some military units. A flag (Arabic: لواء) is equivalent to a brigade in Arab countries, and in Spain, a flag (Spanish: bandera) is a battalion-equivalent in the Spanish Legion.

A flag is a colored cloth with a specified meaning.

Flag is Yello's sixth original album, released in 1988 and featuring the eight-minute tour-de-force, "The Race", the edited version of which reached number 7 in the UK Singles Chart in August of that year. "The Race" was used as a trailer for Eurosport, and the opening theme to the US quiz show It's Academic.

An early cut of the album was used as the soundtrack for the film Nuns on the Run.

is a 13-episode Japanese mecha-genre anime series directed by veteran director Ryosuke Takahashi. It was broadcast as pay per view streaming web video on Bandai Channel starting on June 6, 2006. Episodes 1 and 2 were scheduled to be broadcast on the anime PPV channel SKY Perfect Perfect Choice ch. 160 Anime from August 18, 2006. Stylistically, the series makes use of a still and video cameraman POV, as well as " web cam" images to create a documentary-like narrative, despite being an animated drama. Character design is by Kazuyoshi Takeuchi and mecha design is by Kazutaka Miyatake.

In mathematics, particularly in linear algebra, a flag is an increasing sequence of subspaces of a finite-dimensional vector space V. Here "increasing" means each is a proper subspace of the next (see filtration):

$$\{0\} = V_0 \sub V_1 \sub V_2 \sub \cdots \sub V_k = V.$$
If we write the dim V = d then we have

0 = d < d < d < ⋯ < d = n, 
where n is the dimension of V (assumed to be finite-dimensional). Hence, we must have k ≤ n. A flag is called a complete flag if d = i, otherwise it is called a partial flag.

A partial flag can be obtained from a complete flag by deleting some of the subspaces. Conversely, any partial flag can be completed (in many different ways) by inserting suitable subspaces.

The signature of the flag is the sequence (d, … d).

Under certain conditions the resulting sequence resembles a flag with a point connected to a line connected to a surface.

Flag is singer-songwriter James Taylor's ninth studio album. Released in 1979, it included songs from Taylor's music score to Studs Terkel and Stephen Schwartz's Broadway musical, Working ("Millworker", "Brother Trucker").

The album was not particularly well received, but it did provide a hit in Taylor's cover version of the Gerry Goffin– Carole King composition " Up on the Roof".

The signal flag that makes up the cover of the album is "O (Oscar)", standing for "man overboard".

On the 12 May 1979 episode of Saturday Night Live, James Taylor was the musical guest, and performed three songs from the album, "Up on the Roof", " Millworker", and "Johnnie Comes Back".

In (polyhedral) geometry, a flag is a sequence of faces of a polytope, each contained in the next, with just one face from each dimension.

More formally, a flag ψ of an n-polytope is a set {F, F, ..., F} such that F ≤ F (−1 ≤ i ≤ n − 1) and there is precisely one F in ψ for each i, (−1 ≤ i ≤ n). Since, however, the minimal face F and the maximal face F must be in every flag, they are often omitted from the list of faces, as a shorthand. These latter two are called improper faces.

For example, a flag of a polyhedron comprises one vertex, one edge incident to that vertex, and one polygonal face incident to both, plus the two improper faces. A flag of a polyhedron is sometimes called a "dart".

A polytope may be regarded as regular if, and only if, its symmetry group is transitive on its flags. This definition excludes chiral polytopes.

A flag is a device used in lighting for motion picture and still photography to block light. It can be used to cast a shadow, provide negative fill, or protect the lens from a flare. Its usage is generally dictated by the director of photography, but the responsibility for placing them can vary by region, usually devolving to either the gaffer and electricians or the key grip and lighting grips.

Flags come in a wide variety of shapes and sizes, from mere square inches ("dots and fingers") to many square feet ("meat axes"). Most "industry-standard" flags consist of a square wire frame stitched with black duvetyne, which minimizes any reflected light and keeps the flag lightweight. Flags are distinguished from larger light-cutting tools such as overhead rigs or butterflies in that they can be mounted on individual C-stands, as opposed to being affixed to collapsible frames.

The above notwithstanding, given smaller budgets or extenuating circumstances, virtually any opaque object can be used to flag light.

A smaller variant with an articulated arm, colloquially known as a French flag, is occasionally attached to the movie camera at the discretion of the focus puller solely for the purpose of blocking light flares which the matte box and its accessories cannot reach.

Flag is an encaustic painting by the American artist Jasper Johns. Created when Johns was 24 (1954–55), two years after he was discharged from the US Army, this painting was the first of many works that Johns has said were inspired by a dream of the U.S. flag in 1954. It is arguably the painting for which Johns is best known.

The US flag was in the news repeatedly in 1954. The McCarthy hearings came to a close on 17 June 1954, only three days after Flag Day. On Flag Day, U.S. President Dwight D. Eisenhower signed an amendment to the pledge of allegiance to add the words "under God." The New York Times ran article on facts and myths associated with the flag on the day before Flag Day, and then an article on the "discipline" of the flag on Flag Day itself, saying, with reference to a national air-raid drill "we are all soldiers now". Francis Scott Key, composer of " The Star Spangled Banner", was born in 1779, exactly 175 years before 1954. The Iwo Jima Marine Memorial at Arlington National Cemetery, with its large US flag, was dedicated on 11 November 1954. Johns and his father were both named after Sergeant William Jasper, who saved the fallen flag of the Americans at Fort Moultrie in the American Revolutionary War.

The work measures by . It is made using encaustic, oil paint, and newsprint collage on three separate canvases, mounted on a plywood board. The painting reflects the three colors of the US flag: red, white and blue; the flag is depicted in the form it took between 1912 and 1959, with 48 white stars on a blue canton representing the then-US states (excluding Alaska and Hawaii), and with thirteen red and white stripes. Newsprint is visible under the stripes. Reading the texts, it is clear that the newsprint was not selected at random: Johns steered clear of headlines, or national or political news, and used inconsequential articles or adverts. The painting has a rough-textured surface, and the 48 stars are not identical. It is dated 1954 on its reverse.

Johns's selection of the US flag allows him to explore a familiar two-dimensional object, with its simple internal geometric structure and a complex symbolic meaning. Johns was attracted to painting "things the mind already knows", and claimed that using a familiar object like the flag freed himself from the need to create a new design and allowed him to focus on the execution of the painting. Critics were unsure whether it was a painted flag or a painting of a flag; Johns later said it was both. His work is often described as Neo-Dadaist and anticipates aspects of pop art, minimal art, and conceptual art.

Johns made over 40 works based on the US flag, including a large and monochrome White Flag in 1955, and his 1958 work Three Flags with three superimposed flags showing a total of 84 stars.

In November 2014 the encaustic Flag (1983) was auctioned off for $36,000,000 at Sotheby's New York.

The painting was included in Johns's first solo exhibition at the Leo Castelli Gallery in early 1958. Alfred Barr, director of the Museum of Modern Art, wanted to buy the work, but was concerned that it might be considered unpatriotic. He persuaded a friend, Philip Johnson, to buy it instead; Johnson bought it, and donated it to the Museum of Modern Art "in honor of Alfred H. Barr, Jr." when he retired in 1968.

FLAG is an acronym for a chemotherapy regimen used for relapsed and refractory acute myeloid leukemia (AML). The standard FLAG regimen consists of:

1. FLudarabine: an antimetabolite that is not active toward AML, but increases formation of an active cytarabine metabolite, ara-CTP, in AML cells;
2. High-dose cytarabine (Arabinofuranosyl cytidine, or ara-C): an antimetabolite that has been proven to be the most active toward AML among various cytotoxic drugs in single-drug trials;
3. Granulocyte colony-stimulating factor (G-CSF): a glycoprotein that shortens the duration and severity of neutropenia.

FLAG and FLAG-based regimens can also be used in cases of concomitant AML and either acute lymphoblastic leukemia (ALL) or lymphoma. Because fludarabine is highly active in lymphoid malignancies, these regimens can further be used when patients have biphenotypic AML, in which cells display properties of both myeloid and lymphoid cells.

Flag crater is a small crater in the Descartes Highlands of the moon visited by the astronauts of Apollo 16. The name of the crater was formally adopted by the IAU in 1973. Geology Station 1 is adjacent to Flag, at the much smaller Plum crater.

On April 21, 1972, the Apollo 16 lunar module (LM) Orion landed about 1.5 km east of Flag, which is between the prominent North Ray and South Ray craters. The astronauts John Young and Charles Duke explored the area over the course of three EVAs using a Lunar Roving Vehicle, or rover. They drove to Flag on EVA 1.

Flag crater is approximately 240 m in diameter and over 20 m deep. The adjacent crater Plum is only about 30 m in diameter. The slightly larger crater Spook, also visited by the astronauts, lies less than 1 km to the east.

Flag cuts into the Cayley Formation of Imbrian age.
