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.

Doriathrin

lind

noun/adjective. tuneful, sweet; *singing

An adjective meaning “tuneful, sweet” developed from primitive ᴹ✶lindā (Ety/LIND, EtyAC/LIND). It is an example of how the usual Ilkorin a-affection was prevented or reverted before [nd], as suggested by Helge Fauskanger (AL-Ilkorin/lind). This word may also have had the sense “✱singing” in the word myrilind “nightingale = ✱night singing”, from primitive ᴹ✶lindē.

line

noun. pool

A noun for “pool” derived from the root ᴹ√LIN (Ety/LIN¹). Its Quenya cognate ᴹQ. linya suggests its primitive form was ✱✶linyā [linjā]. If so, it is an example of how, after [[ilk|final [a] was lost]], the [[ilk|final [j] became [i]]] and then became [e], as suggested by Helge Fauskanger (AL-Ilkorin/line).

myrilind

noun. nightingale

The Ilkorin noun for “nightingale”, appearing as both murilind and myrilind (Ety/MOR, TIN). Its Quenya cognate ᴹQ. morilinde indicates a primitive form of ✱✶morilindē, further supported by the rejected Ilkorin form morilind (EtyAC/MOR). This would have produced murilind according to the rules of Ilkorin i-affection. The variant form myrilind hints at a different (dialectical?) phonetic development, as pointed out by Helge Fauskanger (AL-Ilkorin/murilind). See the entry on i-affection for further discussion.

gelu

adjective. (pale) blue

A Doriathrin adjective meaning “(pale) blue” derived from the root ᴹ√ƷEL (Ety/ƷEL), probably from a primitive form ✱✶ʒelwā [ɣelwā] based on its cognates. If so, the [[ilk|initial [ɣ] became [g]]], the [[ilk|primitive final [a] vanished]], after which the [[ilk|final [w] became [u]]]. These developments were noted by Helge Fauskanger (AL-Doriathrin/gelu).

moth

noun. pool

A Doriathrin noun for “pool”, derived from root ᴹ√MBOTH (Ety/MBOTH). Its Quenya cognate ᴹQ. motto suggests a primitive form of ✱✶mbottʰō. As pointed out by Helge Fauskanger (AL-Doriathrin/moth), the primitive [mb-] might be expected to have become [b-], since initial nasals usually vanished before stops in Ilkorin, as for example Ilk. bril < MBIRÍL.
