Forms

hilo m (plural hilos)[1] Old Spanish wrote filo; the DCECH has no example of hilo before Nebrija, while Alfonso de Palencia still writes filo.[2][3]

Etymology

It is inherited from Old Spanish filo, inherited from Latin fīlum (“thread”).[2][4][5][1] The forms with /f/ held on in the transferred sense “cutting edge of a blade”, unknown in Latin but common to the western Romance languages, and Spanish used the difference to keep filo “edge” apart from ⟨hilo⟩ “thread”.[2][1] Corominas calls ⟨filo⟩ an archaic or foreign doublet;[1] Wiktionary notes that both words were inherited and that it is not fully clear why they split.[4][1]

The same Latin word is Portuguese fio, Galician fío, Asturian filu, Catalan fil, French fil, Italian filo and Romanian fir.[6][7][1] The word Basque firu “thread” comes from it too.[2][7] The Latin plural fīla survives in hila, once “row”, later “lint for dressing wounds”.[2][4]

fīlum goes back to Proto-Italic *fī(s)lo- and Proto-Indo-European *gʷʰiH-(s-)lo- (“sinew, sinew thread”).[8][1] Its cognates include Lithuanian gýsla (“vein, sinew”), Armenian ջիլ (ǰil, “sinew”) and Welsh gïau (“sinews”).[8][1]

Earliest recorded meaning

Corominas's first record is a 13th-century Bible manuscript in the Escorial (I-j-8), though he has no doubt the word was in use from the beginnings of the language.[2][4] The Fuero de Zorita de los Canes (1218–c. 1250) rules that the warp of a cloth have setenta et VIII cuerdas, et las cuerdas ayan çient filos “seventy-eight cords, and the cords a hundred threads each”.[3] The Moamín (1250) prescribes sewing con filo de algodón, ca el filo del lino romperlos yé aýna “with cotton thread, for linen thread would soon tear them”.[3]

Semantic evolution

Alfonso X's astronomy also uses filo for a line of stars and for the plumb line of a quadrant.[9] The sense “cutting edge” is first recorded in 1490, in Alfonso de Palencia, with the form filo.[4][2] Covarrubias (1611) records colgar de un hilo “to hang by a thread”, of weak hopes, correr hilo a hilo of a liquid that runs in a thin stream and the proverb por el hilo se saca el ovillo “from the thread you get the ball”.[10] Autoridades defines it as thread of linen, wool or hemp, by antonomasia of linen, and adds metal wire, a thin stream of liquid and, figuratively, the continuation of something (el hilo de la risa).[11]

Echegaray (1887–1889) adds linen clothes as against cotton ones.[12] The DLE now also uses hilo for a chain of messages on one subject in an internet forum or social network.[5][1] In the Americas hilo is recorded from 1512 in Puerto Rico (hilo de ballesta “crossbow string”); in the Canaries a hilo de agua was a measure of a water flow.[13][14]
