Pronunciation

Forms

épineux (feminine épineuse, masculine plural épineux, feminine plural épineuses)[1] Old French espinus and espineus;[2][1] épineux from 1636 (Monet).[2][1]

Etymology

It is inherited from Old French espineus, inherited from Latin spīnōsus (“covered with thorns, prickly, subtle”), from spīna (“thorn”) (the source of épine).[3][4][5][6][1]

Cognate with Old Occitan espinos, Italian spinoso, Spanish espinoso and Portuguese espinhoso.[7][5]

Earliest recorded meaning

Philippe de Thaon's Bestiaire (1121–1134) has Espinuse at la pel “it has a thorny skin”, in the concrete sense “covered with thorns”.[3][4]

Semantic evolution

The concrete Latin sense came first, and in the 20th century the word also became a noun for a thorny shrub (1945).[4][3] A figurative sense “stinging” (before 1328) has become rare.[4][3]

Of a person it meant “off-putting, always making difficulties” (1458),[3][4] and of a thing “full of difficulties”, the common modern sense of question épineuse, from the 15th or 16th century.[4][8] In anatomy Paré used it in 1561 for parts related to the spine, as in the muscle called épineux.[3][7]
