A noun meaning “ground, floor” derived from the root ᴹ√TALAM (Ety/TALAM). Most likely it developed from primitive ✱✶talama, first losing the second [a] due to the Ilkorin syncope and the final [a] when short final vowels vanished, after which the resulting [[ilk|final [m] became syllabic and developed into [um]]]. These developments were suggested by Helge Fauskanger (AL-Ilkorin/talum).
