Forms

seda f (countable and uncountable, plural sedas)[1] Houaiss records seedas in the 14th century and çeda in the 15th.[2] The spelling sêda was used before the spelling reforms.[1]

Etymology

It is inherited from Latin saeta (“bristle, horsehair”), also spelt ⟨sēta⟩.[2][3][4][5][1] In Latin the word meant only the coarse hair of pigs and horses, a brush of bristles and a fishing line;[6][7][8] Corominas and Aurélio suppose that in the Middle Ages it was applied to silk thread, which was then imported as thread.[6][7][8] The sense “silk” is not found in Latin writers or glossaries, and Du Cange's first examples are from 1118.[6] Nascentes cites an older view that silk was called ⟨saeta serica⟩, “hair of the Seres”, the people of eastern Asia, and then simply ⟨seta⟩;[4] Lokotsch saw a chance meeting of the Latin word with a Medieval Latin seta of the Middle Ages modelled on a Chinese word for silk.[4]

The same Latin word is Galician seda, Spanish seda, Catalan seda, Occitan seda, Italian seta and French soie.[9][4] Early Romance passed it in the 8th or 9th century to Old High German sida, whence German Seide, and to Old English side.[6]

The Latin noun goes back to *saitā and Proto-Indo-European *séh₂ito- (“cord”), from a root meaning “to bind”, with cognates such as Lithuanian saĩtas (“tie”) and seid (“cord”).[10][1] De Vaan notes that Schrijver finds the link between “cord” and “hair” doubtful, but thinks the metaphor easy.[10]

Earliest recorded meaning

Lorenzo's first records are in the Cantigas de Santa Maria: pano de seda, “silk cloth”, and babous que crian a seda, “worms that breed silk”;[11] Machado's first date had been 1388.[11] The Crónica Troiana has a bed strung dũas cordas anchas de seda, where the DDGM leaves open whether silk or bristle is meant.[11] Houaiss and Cunha date the word to the 13th century.[2][3]

Semantic evolution

Portuguese has kept the Latin sense “bristle” beside “silk”, which Spanish has mostly replaced with cerda.[6] Morais in 1813 lists both: silk and the silk cloths made of it, and the hairs of the beard, tail and body of animals, the bristles that shoemakers fix to the end of their thread.[12] Houaiss dates the plural sedas “coarse animal hairs” to before 1635.[2] Bluteau repeated a derivation from a Hebrew word Sericoth.[13]

Later senses are a crack or flaw in a metal plate or tool, the horsehair of a violin bow, and in Brazil a very gentle person and the paper used to roll a cannabis cigarette.[2][14][1]
