A verb in The Etymologies of the 1930s appearing in its Noldorin-style infinitive form N. rheði “to sow” under the root ᴹ√RED “scatter, sow” (Ety/RED).
Neo-Sindarin: Since initial *r* unvoiced to *rh* in Noldorin of the 1930s but not in Sindarin of the 1950s and 60s, most Neo-Sindarin writers adapt this word as ᴺS. redh- “to sow”, as suggested in HSD (HSD).
This root first appeared as ᴹ√RED “scatter, sow” in The Etymologies of the 1930s along with augmented variant ᴹ√ERÉD and derivatives like ᴹQ. erde/N. eredh “seed, germ” and ᴹQ. resta/N. rîdh “sown field, acre” (Ety/ERÉD, RED). √RED appeared again in the Outline of Phonology (OP2) from the early 1950s with the same gloss “scatter, sow” and derivatives Q. resta/S. rîdh “sown field” (PE19/91). The Quenya word resta reappeared in the 1964 phrase Q. nai elen siluva parma-restalyanna meldonya “✱may a star shine upon your book-fair, my friend” (VT49/38), which might indicate the ongoing validity of this root, but it is also quite possible that resta “✱fair” has a completely different etymology.
