thole (v.)
"to be subjected to or exposed to, to endure without complaint," now Scottish and Northern English dialect, from Old English þolian "to suffer, endure, undergo; remain, survive; to lose, lack, forfeit," from Proto-Germanic stem *thul- (source also of Old Saxon tholon, Old High German dolon, Old Norse þola, Gothic þulan "to suffer," German geduld "patience"), from PIE *tele- "to bear, carry" (see extol).
thole (n.)
"peg," from Old English þoll "oar-pin," from Proto-Germanic *thulnaz (source also of Old Norse þollr, Middle Low German dolle, East Frisian dolle, Dutch dol), of unknown origin; according to Watkins probably from Proto-Germanic *thul-, from PIE root *teue- "to swell," on the notion of "a swelling." No record of the word in English from c. 1000 to mid-15c.
