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.
aman
noun. mother
cwend
noun. Elf
A Doriathrin noun meaning “Elf” derived from primitive ᴹ✶kwenedē (EtyAC/KWEN(ED)), an example of the Ilkorin syncope.
Conceptual Development: This word is nearly identical to earlier Gnomish Cwenn “Elf” before Tolkien revised the phonological history of the Noldorin language so that [[on|[kw] became [p]]].
gwedh
noun. bond
A noun meaning “bond” derived from primitive ᴹ✶wedā (Ety/WED). Here the [[ilk|initial [w] became [gw]]], and the [[ilk|[d] spirantalized to [ð]]].
Below: Tolkien's Late Period (1950–1973). These are from Tolkien's late conceptual period — his most settled forms of the languages. Prefer these over the earlier ones above when composing new text.
Ilkorin for “mother” (Ety/AM¹), also appearing in its plural form emnin (EtyAC/AM¹).
