ᴱN. urrost adj. “never coming to life” (Category: to Live; Living; Life)
A word in Early Noldorin Word-lists of the 1920s glossed “never coming to life” (PE13/156), replacing a rejected form ᴱN. uvrost “dead with hope of resurrection” that uses the abandoned negative suffix ᴱN. um- rather than ᴱN. ur- (PE13/155). Its second element probably means something like “rising”, hence = “*never rising”.
