Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!
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”.
