√TA root. “that, there, then; demonstrative”
Tolkien used the root √TA for Elvish demonstratives for much of his life, but in the Qenya Lexicon of the 1910s, ᴱ√TA “demonstrative” (with variant ᴱ√TAMA²) had derivatives like ᴱQ. tāma “this” and ᴱQ. tamīne “today” (QL/87). This ᴱ√TA seems to be a near demonstrative “this”, as opposed to ᴱ√E “that (by you)” for far demonstratives (QL/87), the latter reappearing in later writings as a “very far” demonstrative ᴹ√EN “yonder, over there”.
By The Etymologies of the 1930s, ᴹ√TA had switch from “this” to “that”, with derivatives like ᴹQ. tana “that (anaphoric)” and ᴹQ. tar/ON. tō “thither” (Ety/TA). √TA continued to appear regularly in Tolkien’s later writings with senses like “that, there, then”.
