mir

root. *precious

mazgō

noun. sticky substance, mire

tyal

root. play

This root first appeared as ᴱ√TYALA “play” in the Qenya Lexicon of the 1910s with the derivative ᴱQ. tyalie “play, game” (QL/49). Forms in the contemporaneous Gnomish Lexicon like G. dairtha- “play” < ᴱ✶daı̯al- hint that the actual primitive form might have been ✱ᴱ√DYALA or ✱ᴱ√DAYALA (GL/29). In a table of vowel mutations added as a revision to the Gnomish Lexicon Tolkien instead had forms like ᴱ✶táliı̯èndǝ > G. teilian indicating a primitive initial t- (PE13/116); similar forms appeared in the Early Noldorin Dictionary of the 1920s (PE13/165).

In The Etymologies of the 1930s Tolkien gave ᴹ√TYAL “play” with derivatives like ᴹQ. tyal-/N. telia- “to play” and ᴹQ. tyalie/N. telien “sport, play, game” (Ety/TYAL). Tolkien continued to use Q. tyalië “mirth” in later writings (PE21/80; PE17/64), but at some point in the 1950s decided that initial palatalized dentals were no longer a feature of Primitive Elvish (PE18/93-94), making the ongoing validity of √TYAL as a CE root doubtful: see the entry on how [[at|[j] was lost after initial dentals]] in the Welsh-like branch of the Elvish languages for further details. For example, in the second version of Tengwesta Qenderinwa (TQ2) from around 1950, Tolkien indicated √TYAL was a Quenya-only root, an elaboration of √TAL:

> In Quenya initial groups ty, ny, ps, ks appeared as developments of ky, ñy, sp, sk. But being established they were used in new formations. Thus Q tyal- “play” as a variation on tal- (not kal!) (PE18/84).

Neo-Eldarin: For purposes of Neo-Eldarin, I think it is best to ignore Tolkien’s decision to remove initial palatalized dentals from Primitive Elvish in order to retain roots like √TYAL for both Quenya and (Neo) Sindarin.

bányā

adjective. beautiful

kanat

root. four

khyel(es)

root. glass

A root in The Etymologies of the 1930s glossed “glass” with derivatives in both Quenya and Noldorin with the same meaning: ᴹQ. hyelle and N. hele (Ety/KHYEL(ES)). After Tolkien changed Noldorin to Sindarin, he decided that “There was no common Eldarin word for glass”, and that the Sindarin word S. heledh was derived from Khuzdul kheled (PE17/37). Thus the root ᴹ√KHYEL(ES) was abandoned.
