nelm : grove
The Illunse word for grove (wood, small forest) is nelm. Nelm is an uncommon last name. NELM is an acronym for The National English Literary Museum in Grahamstown, South Africa.
This word is a mixture the Latin word nemus (tract of woodland, grove, glade), and the Old English word holt (wood, forest, grove, thicket).
My previous Illunse word for grove was helt. I considered making this word nolm, which is a better mix, but that word seemed too similar to my word for hill, which is holl.
nelmas : groves
The Illunse word for groves (nominative plural) is nelmas.
Groves in Latin is nemoris. Groves in Old English is holtas.
Here's a link to Grove, in J.R.R. Tolkien's words.
