revia : rain
The Illunse word for rain is revia. Revia is an unusual last name. Revia can be a variation of the feminine first name Reva. Revia is a brand-name presciption drug. In Sindarin revia- is a (possibly obsolete) verb meaning to fly, sail; to wander. Revia is the name of a town in Mozambique.
This word is a mixture of the Old English word for rain which is regn and the Latin word for rain which is pluvia (rain, shower).
My previous word for rain was rewia. A minor change. In that word I transliterated the V in the Latin word to W. I decided I'd rather keep the V instead.
