flag

Etymology and origin of the English word flag

English has four words spelled flag: the banner, the iris plant, the verb “to droop, tire”, and the flat paving stone, from Old Norse.[1][2] Their origins are mostly uncertain, and the banner and the verb may be connected.[1][2][3]

Pronunciation

  • IPA: /flæɡ/[4]

flag1 banner

Confidence
Unknown
First attested
1530

Etymology

Its origin is uncertain.[1][5][2] The word is in all the modern Germanic languages, as Danish flag, Swedish flagga, Dutch vlag and German Flagge, but seems to be recorded first in English, which may be their source.[1][5] It is perhaps from the obsolete adjective flag “hanging down”,[2][3] or related to the verb flag “to flap about”,[1][5] or an independent imitative word for something flapping in the wind, as the OED suggests.[5][3] Merriam-Webster connects it with fag end.[6]

Earliest recorded meaning

1530, in Palsgrave's Lesclarcissement, and perhaps as early as 1481, according to Barnhart;[1] the late 15th century in Etymonline,[5] the mid-16th century in Word Origins.[3]

Semantic evolution

The verb, to stop by waving a flag, is from 1856 in American English,[1][7] and to decorate or mark with flags from the late 18th century.[8] Show the flag, from the early 20th century, was first said of a naval ship making an official visit to a foreign port.[3] The American Flag Day, from 1894, marks the adoption of the Stars and Stripes on June 14, 1777,[5] and the name and details of a newspaper are its flag from 1956.[5]

Confidence
Unknown

Etymology

Its origin is unknown.[7][2] It is perhaps a variant of Middle English flakken “to flap, flutter”,[1][5] probably from Old Norse flaka “to flicker, flutter, hang loose”, itself perhaps imitative.[5][1] Hoad relates it to the obsolete adjective flag “hanging loose”.[2]

Earliest recorded meaning

“To flap about loosely, hang down”: 1545 in Barnhart and Merriam-Webster Unabridged,[1][7] the 1540s in Etymonline.[5]

Semantic evolution

“To become limp, droop” is first recorded in Cotgrave's dictionary of 1611,[1] the 1610s in Etymonline,[5] which led to the sense “to grow tired or weak”.[2][1]
