Ilk. tingla- v. “to sparkle”
A verb meaning “to sparkle” derived from the root ᴹ√TIN (Ety/TIN), mostly likely from a primitive verb *✶tinglā. If so, it is an example of how the Ilkorin a-affection was prevented or reverted before [ŋg]. This development was pointed out by Helge Fauskanger, though he suggested the primitive verb was *✶tintilā, a cognate Q. tintila-, with a medial development of [-nt(i)l-] > [-ngl-] (AL-Ilkorin/tingla-).
