ᴹ√KHAR root. “helmet”
A root in The Etymologies of the 1930s glossed “helmet” with extended forms √KHÁRAP and √KHÁRAN (EtyAC/KHAR); one of its derivatives ᴹQ. Eldahar seems to be a precursor to Q. Eldacar “Elfhelm”. There are many other words for “helmet” in Tolkien’s later writing, and this root was probably abandoned.
