Finduilas

The initial element fin- certainly means 'hair', but the remainder of Finduilas' name is difficult to interpret. In many names the final element -las means 'leaf', and that may be the case here, but it is difficult to see how the concepts of 'hair' and 'leaf' could be meaningfully connected within a name. There may possibly be a connection to duil 'river' (so Finduilas would mean something like 'flowing hair').

It seems reasonable to presume that Finduilas' name was taken from that of Finduilas of Nargothrond, the daughter of Orodreth, who lived and died during the First Age.

Finduilas' elder sister Ivriniel is not mentioned in any canonical work, but she does appear in a genealogical chart in volume XII of The History of Middle-earth
