 Finellach - another name for Gil-Galad (the latter meaning starlight, as Frodo says before Sam sings the song about him around the camp fire).
FIN (French word for end) + ELL (a measure - Sam uses it to measure rope) + ACH (ohhhh - ache without an E - no wonder trying to put PA or PAI into the answer didn't work.  I thought at first it meant "Ach!" as an expression of pain, and couldn't quite work in the "endless" bit).
