Forms

espinoso (feminine espinosa, masculine plural espinosos, feminine plural espinosas)[1]

Etymology

It is inherited from Old Spanish espinoso, inherited from Latin spīnōsus (“thorny, prickly”).[2][3][4][1] Wiktionary also allows a Spanish formation from espina and the suffix -oso, which is how the Spanish Wiktionary explains it.[1][5]

The same Latin adjective is Portuguese espinhoso, Galician espiñoso, Catalan espinós, French épineux, Italian spinoso and Romanian spinos.[6][7] Houaiss derives the Portuguese word from espinho with its suffix, while noting that others take it straight from the Latin.[8]

The Latin adjective is formed from spīna (“thorn”) with the adjective suffix -ōsus.[9][1]

Earliest recorded meaning

Corominas dates the word to a charter of 1166 in Oelschläger's list of first records.[2][3] The Libro de Alexandre (c. 1230–1250) has it in the plain sense “full of thorns”.[10]

Semantic evolution

The sense “thorny, prickly”, said of plants, has been the main one throughout;[11][12] Autoridades illustrates it with Laguna's Dioscorides, where the teasel is counted among the espinosas plantas.[13] The figurative sense “arduous, dangerous, tangled” was recorded by the same dictionary, which says that an affair is called espinoso when it is hard to enter and to unravel.[13] The Academy's later editions kept both senses, calling the second “metaphorical” in 1817 and “figurative” from 1884.[11][12][4]

Terreros (1786–1793) already used espinoso as the name of a fish with spines on its back, the stickleback, and of a muscle.[14] Gaspar y Roig listed the anatomical uses, such as the apófisis espinosas of the vertebrae.[15] In Panama the masculine noun names a tree, the pochote.[16]
