√(Ñ)GAY root. “gape, become wide, open, vast”
A root appearing in notes on words and phrases from The Lord of the Rings from the late 1950s, serving as an explanation for √GAY(AR) “sea” (PE17/27). Its gloss was “gape, become wide, open, vast”, but elsewhere “sea” words were generally attached to roots meaning “awe, dread”, so I think this was likely a transient idea. See the entry on √GAY(AR) for further discussion.
