Forms

viscoso (feminine viscosa, masculine plural viscosos, feminine plural viscosas)[1]

Etymology

It is borrowed from Late Latin viscōsus (“sticky; smeared with birdlime”), formed from Latin viscum (“mistletoe; birdlime”) with the suffix -ōsus.[2][3][4][1] Its popular relative is visco “birdlime”, inherited from the same Latin noun.[5] The Latin adjective is also Italian viscoso, French visqueux, Catalan viscós, Portuguese viscoso, Old Occitan vescos and Romanian vâscos.[6] Aragonese and some Castilian dialects have vescoso.[7]

The Latin noun meant the mistletoe and the birdlime made from its berries.[8] De Vaan compares Ancient Greek ἰξός (ixós, “mistletoe, birdlime”) and words for the sour cherry in Germanic and Slavic, and considers it either an Indo-European word or a European loanword for a fruit-bearing tree.[8] Wiktionary connects it with Proto-Indo-European *weyḱs- and Proto-Slavic *višьňa.[1]

Earliest recorded meaning

The first dated record in the Old Spanish Textual Archive is in Estéfano de Sevilla's medical treatise Visita y consejo de médicos (1381).[9] DEMel cites the feminine viscosa earlier still, in the Castilian Libro del tesoro of the late 13th century, and López de Ayala's book on hunting birds (1386) has it too.[10] The sense has always been “sticky, gluey”.[11][4]

Semantic evolution

Corominas and the BDELC date the word from Alonso de Palencia (1490), together with viscosidad “stickiness”.[2][3] In the Americas it described pools and plant juices in Santo Domingo in the 1540s.[12] The Diccionario de Autoridades (1739) defined it as sticky or glutinous and quoted Mármol on a flesh that was hedionda, y viscosa, “stinking and slimy”.[11] The feminine viscosa now also names viscose, a product of cellulose used for textile fibres.[4] The medical dictionary DTME also defines it as having viscosidad.[13]
