Inherited from

Ultimate origin
Proto-Germanic (*finhlō)

Etymology

The tool is inherited from Middle English file, also vile,[3] inherited from Old English fēol, Mercian fīl,[5][3][2] from Proto-Germanic *finhlō,[3] probably from Proto-Indo-European *peig- (“to cut, mark by incision”),[5][3][2] the source also of Old Church Slavonic pila “file, saw” and Lithuanian piela “file”.[5] It is cognate with Dutch vijl, German Feile and Old Norse þél.[5][3][2] The verb is Old English fīlian.[3][6]

Earliest recorded meaning

A metal instrument for smoothing or shaping: before 800.[3][7] It is the oldest of the English words spelled file.[1]

Semantic evolution

Figurative use, especially of the polish given by a file, is from before 1225.[7] The verb, “to rub or smooth with a file”, is probably from before 1200, in the Ancrene Riwle.[3] In 19th-century slang a file was an artful, shrewd person, from 1812.[7] Nail file is by 1819,[5] and filings is from before 1398.[3]

Borrowing
First attested
1473
Borrowed from
Middle French filer
Ultimate origin
Latin (fīlum)

Etymology

The papers and the row are borrowed from Middle French filer (“to string documents on a wire; to spin thread”),[3][5] and fil (“thread, string”),[3][2] from Latin fīlum (“thread”),[5][3][1] from Proto-Indo-European *gʷhi- (“thread, tendon”).[5] The noun for a row of people is a separate, later borrowing of file (“row”), from filer in the sense “to march in file”, from Late Latin fīlāre “to spin, draw out in a line”.[3][5] Latin fīlum is also behind filament, filigree and fillet.[1]

Earliest recorded meaning

The verb, to put documents on record: 1473 in Barnhart[3] and the mid-15th century in Etymonline.[5] The noun, a string or wire on which documents were hung, is from 1525.[3][5]

Semantic evolution

The notion is of documents hung on a line in order for easy reference;[5] methods have changed, but the word has stuck, which is why things were long said to be on file.[5] To place among the records of a court is from the 1510s.[5] A collection of papers arranged for reference is from 1566 in Barnhart[3] and the 1620s in Etymonline.[5] A line of people or soldiers one behind another, at first military, is from 1598,[3][5] and a line of squares on a chessboard from the 1610s.[5] The computer sense is from 1954, as is the sense of a reporter filing copy.[5]
