haig

noun. way, road, path

A word appearing as haig or haid in the Gnomish Lexicon of the 1910s glossed “way, road, path”, related to the verb G. haitha- “hie, go, fare, walk” (GL/47). These words may be early manifestations of the root ᴹ√KHAYA “far, distant, remote” from The Etymologies of the 1930s (Ety/KHAYA).
