There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.

Middle Primitive Elvish

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.

khyar

root. left hand

A root given as {ᴹ√KHAR >>} ᴹ√KHYAR “left hand” in The Etymologies of the 1930s, associated with ᴹQ. hyarmen/N. harad “south” (Ety/KHYAR). These words for “south” reappeared in The Lord of the Rings (LotR/1115), and the connection between “south” and “left” was reaffirmed in Tolkien’s discussion of the Ambidexters Sentence from the late 1960s, since the Elves aligned the cardinal directions by facing west towards Aman (VT49/6-8).
