Ilk. tû n. “muscle, sinew; vigour, physical strength” (Category: Strong, Mighty, Powerful)
A noun meaning “muscle, sinew; vigour, physical strength” derived from primitive ᴹ✶tūgu with an attested intermediate form tūgh [tūɣ] (Ety/TUG). It is a good example of how [g] spirantalized to [ɣ] (“gh”) after a vowel, and the resulting voiced velar spirant [ɣ] vanished, as suggested by Helge Fauskanger (AL-Ilkorin/tû).
