thorn: [OE] Thorn is an ancient word, which goes all the way back to an Indo-European *trnus. The Germanic descendant of this was *thurnuz, which evolved into German dorn, Dutch doorn, Swedish and Danish torn, and English thorn.
thorn (n.)
Old English torn "sharp point on a stem or branch," earlier "thorny tree or plant," from Proto-Germanic *thurnuz (cognates: Old Saxon, Old Frisian thorn, Dutch doorn, Old High German dorn, German Dorn, Old Norse torn, Gothic taurnus), from PIE *trnus (cognates: Old Church Slavonic trunu "thorn," Sanskrit trnam "blade of grass," Greek ternax "stalk of the cactus," Irish trainin "blade of grass"), from *(s)ter-n- "thorny plant," from root *ster- (1) "stiff" (see stark).
Figurative sense of "anything which causes pain" is recorded from early 13c. (thorn in the flesh is from II Cor. xii:7). Also an Anglo-Saxon and Icelandic runic letter (t), named for the word of which it was the initial (see -th-).
