hwá

noun. violent wind

hwarwa

noun. violent wind

A word for “violent wind” in notes from the late 1950s with variants hwá and hwarwa, based on a strengthened form of the root √ “blow”: ✶swa-swa (NM/237). I think the longer form hwarwa is preferable.

hwesta

breeze, breath, puff of air

hwesta (1) noun "breeze, breath, puff of air" (SWES), also name of tengwa #12 (Appendix E, VT46:17); hwesta sindarinwa "Grey-elven hw", name of tengwa #34 (Appendix E).

hwesta

noun. breeze, breeze; [ᴹQ.] breath, puff of air

A noun in Appendix E of The Lord of the Rings glossed “breeze”, the name of tengwa #12 [c] (LotR/1123).

Conceptual Development: ᴹQ. hwesta “breath, breeze, puff of air” appeared in The Etymologies of the 1930s as a derivative of the root ᴹ√SWES “noise of blowing or breathing” (Ety/SWES).
