ᴹ√INIK root. “*idea”
A root in The Etymologies of the 1930s given as ᴹ√INK and ᴹ√INIK, the latter marked with a “?” but probably representing the actual form of the root (Ety/INK). The root was unglossed, but its derivatives all seem to be related to the sense “idea” such as ᴹQ. inka “idea”, ᴹQ. intya [< inkya] “guess, supposition, idea, notion” and N. inc “guess, idea, notion” (Ety/INK; EtyAC/INK). It might be connected to the later root √IN(ID) “mind” from 1957 (PE17/155).
