An adjective appearing as G. lendriol or lenthol “coming, approaching” in the Gnomish Lexicon of the 1910s (GL/53). The first is probably an elaboration of len “come, arrive”, and the second is probably a participle form of lentha- “come towards speaker, approach, draw near”.

Neo-Sindarin: For purposes of Neo-Sindarin, I would instead use the active participle ᴺS. tolol “coming, approaching”.
