Gnomish

gwindod

noun. elder tree; elderberry

A word appearing as G. gwindod “elder tree; elderberry” in the Gnomish Lexicon of the 1910s, a combination of G. gwin “woman” and G. dod “berry”, hence more literally “✱woman berry” (GL/45).

Neo-Sindarin: For purposes of Neo-Sindarin, I would update this word to ᴺS. gwennod “elder tree; elderberry, ✱(lit.) maiden berry” using the later word S. gwend “maiden”.
