Pronunciation

Forms

filet m (plural filets)[1] Old French filet, also fillet.[2][3]

Etymology

It is formed from French fil (“thread”) + -et, a diminutive “little thread”, the base noun being from Latin filum (“thread”).[2][4][5][6][7]

The sense “net” has a separate source: it is an alteration of Old French filé “work made of threads” (13th century), the noun use of the past participle of filer,[5][6][8] still written so by Monet in 1636, and matching Old Occitan filat.[5]

Cognate with Occitan filet, Spanish filete and Italian filetto.[9]

Earliest recorded meaning

Marie de France's Fables (about 1180) use it for a thin thread.[2][6][10]

Semantic evolution

From “thin thread” the word took several technical senses: the fold of membrane under the tongue (about 1290),[2][6] and later senses in bookbinding and of the thread of a screw (1690).[6] It also came to mean a thin, steady flow, first of a liquid (1306–1307) and of melted sugar (about 1393),[2][6] and figuratively un filet de voix (1680).[6][10]

About 1393 the Ménagier de Paris uses it for the long cut of meat taken along the backbone, a reference to its long shape and perhaps because the piece was often rolled and tied with string;[2][6] filet mignon appears in 1716–1718.[10][6] English fillet (early 14th century) was taken from Old French filet, and its sense “cut of meat or fish” dates from the late 14th century.[11]

From filé, the word came to mean a mesh of threads (1461), especially for catching animals (16th century), and figuratively a trap (1615).[6] Nets for holding things (1690) and the net of ball games such as tennis (1877) followed.[6]
