suiva
adjective. soughing, moaning
A word appearing as ᴱQ. suiva “soughing, moaning” in Qenya Lexicon of the 1910s, an adjectival form of ᴱQ. sú “noise of wind” (QL/86). The word “soughing” is the present participle of the archaic English verb “sough” meaning “make a moaning, whistling, or rushing sound (of the wind in trees, the sea, etc.)”.
Neo-Quenya: Since Q. sú “sound of wind” reappeared in later writings (VT47/12), I think ᴺQ. suiva can also be used in Neo-Quenya to describing something with a moaning, wind-like sound.
