Etymology

Calque of Latin cervī spīna (“deer's thorny shrub”), cervi (“deer's”) being the genitive singular of cervus (“deer”), from Proto-Italic *kerwos, from Proto-Indo-European *ḱr̥h₂wós, from *ḱerh₂- (“horn”) + *-wós, spīna (“thorny shrub”) from Proto-Italic *speinā, from Proto-Indo-European *spey- (“sharp point”). By surface analysis, buck + thorn.
