Qenya 

roita-

verb. to pursue, to pursue, *chase

A verb in The Etymologies of the 1930s glossed “pursue” under the root ᴹ√ROY “chase” (Ety/ROY).

Conceptual Development: The Qenya Lexicon of the 1910s had a similar verb ᴱQ. rawa- “run, chase” under the early root ᴱ√RAẆA (QL/79). This same document also had ᴱQ. rauta- under the early root ᴱ√RAVA; this verb’s primary meaning was “chase, hunt, pursue”, with secondary meaning “extirpate, exterminate” (QL/79).
