Ilk. thrôn adj. “stiff, hard”
An adjective meaning “stiff, hard” derived from primitive ᴹ✶starāna (Ety/STARAN). First the unstressed vowel in the first syllable vanished to produce the favored combination [tr], after which the initial [s] spirantalized the following [t] to [θ] (“th”), while the long [ā] became [ō]. All these developments were suggested by Helge Fauskanger (AL-Ilkorin/thrôn).
