Nerdanel (name)

The name Nerdanel is given no clear meaning or etymology in the published writings of Tolkien. The original (rejected) version of her name was Istarnië.

Editor and linguist Patrick H. Wynne has suggested that the element nerd- in Nerdanel perhaps derives from nerdo ("large, strong man"), noting that the name "might refer to her strength of body and mind, and her pursuits of crafts more commonly practiced by men." Wynne also suggests that Istarnië derives from Quenya ista- ("know"), apparently "_referring to her 'desire for knowledge".
