An adjective for “powerful” in the Qenya Lexicon of the 1910s under the early root ᴱ√TURU “am strong” (QL/96).
Neo-Quenya: Since √TUR remains connected to power in Tolkien’s later writings, I’d retain this word for purposes of Neo-Quenya, but I’d use it for general or abstract forms of potency, as opposed to being physically powerful (turca or [ᴹQ.] poldórea) or politically powerful (túrëa). For example: turwa nus “a powerful smell” or turwa vangwe “a powerful storm”.
