rant

The sense of "vein" was attested in Noldorin. Because it is very close to the meaning of Latin "vēna", both sharing a sense of "lode" and "vein", I think its meaning as "vein" should be restored in Sindarin. I also think that it should be the general word for "blood vessel", in which case it would initially mean a blood vessel in general, then develop the specialised meaning "vein" once a separate term for arteries emerges. See "davrant" for a neologism for that term.
