mentië

mentië noun "passage, journey, direction of travel" (PE17:13); the elements are men- "go, proceed" + tië "path, road". Not to be confused with the gerund of menta- #1.
menta- (1) vb. "send, cause to go" (in a desired direction) (VT41:6, VT43:15). A similar-sounding primitive verb mentioned in PE17:93 is said to have past and perfect forms that would produce Quenya *mennë*, eménië, but here Tolkien seems to be discussing a distinct intransitive verb "go" and its Sindarin descendants, and Quenya menta- rather belongs to the causative (transitive) verbs which according to the same source has "weak" past-tense forms (in -në, hence mentanë "sent", and likely ementië** as perfect "has sent").
