A Sindarin word for “lofty” mentioned as the equivalent of Q. tára “tall”, proof that the primitive form was ✶tagra < √TAƷ since aʒr > air and then aer in Sindarin, but aʒr > ār in Quenya (PE17/186).
Conceptual Development: The Etymologies of the 1930s had ON. tōra “lofty” as the equivalent of ᴹQ. tára “lofty, high” under the root ᴹ√TĀ/TAƷ (Ety/TĀ; EtyAC/TĀ), but due to differences in the primitive form in ᴹ✶tārā in the 1930s, this produced N. taur which blended with primitive ᴹ✶taurā < ᴹ√TUR to gain the senses “vast, mighty, overwhelming, awful; high, sublime” (Ety/TUR).
Earlier still, the Gnomish Lexicon of the 1910s had G. dara “lofty” (GL/29) equivalent to ᴱQ. tára “lofty” (QL/87). In this period the root likely began with D, as in ✱ᴱ√DAHA, since in Early Qenya of the 1910s, primitive initial voiced stops were unvoiced [ᴱ✶d- > ᴱQ. t-].
adj. Q. tāra.
