fuinë noun "deep shadow" (PHUY; cf. "Qenya" fuin "night" in MC:221). According to VT41:8, fuinë is not a Quenya form at all, but Telerin for Quenya huinë (but unquestionably, fuinë is quoted as a Quenya form in certain earlier sources; cf. also Fuinur below - perhaps we may assume that fuinë was borrowed into Quenya from Telerin and thus came to co-exist with huinë?
