An noun appearing as G. lenthos or lendri “coming, approaching” in the Gnomish Lexicon of the 1910s (GL/53). The first is probably a noun form of lentha- “come towards speaker, approach, draw near”, and the second is probably an elaboration of len “come, arrive”. The form lenthos was first given as (deleted) lend.
Neo-Sindarin: For purposes of Neo-Sindarin, I would instead use the verbal nouns ᴺS. toled “coming, approaching”.
