@@@ this is the proper phonetic evolution of Primitive rikta- assuming vocalization of spirants occurs before a-affection (and in any case, a-affection doesn't apply to verb forms), but because it conflicts with rítha-, Elaran agreed that the neologism rig- might be better

Wife of Huor and mother of Tuor (S/148), her name seems to be a compound of rî “crown” and ann “gift”, though it could also be rían “queen” used as a name.
Conceptual Development: When it first appeared in Silmarillion drafts from the 1930s, this name was N. Rían (SM/35) but in later drafts it appeared as N. Rian with a short i (LR/131), which was its usual form in this period. In The Etymologies it appeared as N. Rhian glossed “Crown-gift”, which is the source of the gloss and derivation given above (Ety/RIG). In Silmarillion revisions from the 1950s-60s, the form S. Rían with a long í was restored (WJ/52).
