Pronunciation

Forms

fir n (plural fire)[1]

Etymology

It is inherited from Latin fīlum (“thread”).[2][3][4][5][6][1][7] De Vaan derives the Latin word from Proto-Indo-European *gʷʰiH-(s-)lo- (“sinew, sinew thread”).[8][1]

The noun survives south of the Danube: Aromanian hir and Megleno-Romanian ir.[2][9][10] Its Romance cognates include Italian filo, Sardinian filu, French fil, Spanish hilo and Portuguese fio.[2][7][11] Albanian fill is a loan from the same Latin word.[12]

Earliest recorded meaning

Tiktin's first record is from 1508, in the Slavonic–Romanian documents.[13] MDA2 dates it to before 1588, from a text in Hasdeu's Cuvente den bătrâni.[3]

Semantic evolution

The word first named spun thread and its fibres, then anything long and thin: a spider's thread, a single hair, a blade of grass or a stalk.[6][4] Gold and silver thread for embroidery is also fir; in that sense the plural is firuri.[4][14] Wire for the telegraph followed French fil télégraphique.[15] The Lexicon de la Buda (1825) gives thread, a hair, a grain and a string of beads.[16]

Figurative senses are the thread of a story and the thread of life;[17][6] Costinescu notes in 1870 that poets speak of firul vieții, like French le fil de la vie, and the DA links it to the spinning of the Fates.[17][6] Regionally a fir is one specimen of a kind: in Muntenia nici un fir de vacă “not a single cow”.[18] In Maramureș în firu-n dinte describes thin, cheap cloth.[19] A recent sense is a lane of road traffic, recorded from 1982.[20]
