ᴹ√GAYAS root. “fear”
A root in The Etymologies of the 1930s glossed “fear” (Ety/GÁYAS). One of its derivatives, N. gaer “dreadful” (< ᴹ✶gaisrā), was given a new etymology in the Quendi and Eldar essay of 1959-60, where S. gaer “awful, fearful” was derived from ✶gairā (WJ/400). However, it is conceivable that √GAYAS could have survived as an extension of the later root √GAY “astound, make aghast”.
