len

adjective. come, arrived

An adjective appearing as G. len “come, arrived” in the Gnomish Lexicon of the 1910s (GL/53), likely based on the early root ᴱ√LEHE “come, be sent, approach” (QL/52). Tolkien said it was “used also with the forms im, on [emphatic pronouns], etc., as a perfect. ‘I have or am come’ as im len, um lenin, etc.”.

Neo-Sindarin: For purposes of Neo-Sindarin, I would instead use the perfective active participle ᴺS. túliel “having come, having arrived”.
