A noun given as raef or raew “net” in notes on The Rivers and Beacon-hills of Gondor from the end of the 1960s based on the root √RAY “net, knit, contrive network or lace; involve in a network, enlace”, a blending of the ancient forms of its Quenya equivalents Q. raima “net” and Q. raiwë “lace” (VT42/12). In a draft of this etymology appearing in Late Notes on Verb Structure (LVS) from 1969, the only form given was raef, equivalent to Q. raima “a net” (PE22/159). Since usually final -m > -f [v] > -w after the diphthong ae, I suspect raef is an archaic form and raew is modern Sindarin.
