The Qenya Lexicon of the 1910s had an adjective ᴱQ. kapalima “bounding, leaping” under the early root ᴱ√KAPA “leap, spring” (QL/45). It also had ᴱQ. haloite “leaping” under the early root ᴱ√HALA (QL/39).

Neo-Quenya: Neither of these early words work for purposes of Neo-Quenya, since -ima means “able to done” in Tolkien’s later writings and the root √KHAL changed in meaning. I would blend these into ᴺQ. capaitë “leaping, bounding”, as combination of [ᴹQ.] kap- “jump” with the suffix -itë “apt to do”.
