Ilk. tovon adj. “lowlying, deep, low”
An adjective meaning “lowlying, deep, low” derived from primitive ᴹ✶tubnā (Ety/STAB). The short [u] became [o] before the final [a], while the [b] spirantalized to [v] after a vowel, with the [n] becoming syllabic and developing into [-on] after it became final. These developments were all suggested by Helge Fauskanger (AL-Ilkorin/tovon).
