quapta- vb. “exchange” (QL:76); quaptalënoun “exchange”
quárë (also quár) noun "fist" (SA:celeb, KWAR; in the Etymologies, Tolkien first wrote quár pl. quari, and quár is also found in PM:318 and VT47:8, in the latter case changed from quárë, VT47:22. As usual, the spelling of the Etym forms shows q instead of qu.) According to PM:318 and VT47:8, the "chief use [of this word] was in reference to the tightly closed hand as in using an implement or a craft-tool rather than to the 'fist' as used in punching".
quárelënoun “watchfulness, anxiety” (QL:76)%
quat- vb. "fill" (WJ:392), future #quantuva "shall fill" (enquantuva "shall refill") (Nam, RGEO:67)Irrespective of the prefix en- "re", the form enquatuva(VT48:11) displays the expected future tense of quat-. The Namárië form enquantuva seems to include a nasal infix as well, which is possibly an optional feature of the future tense. On the other hand, PE17:68 cites the verb as quanta- rather than quat-, and then the future-tense form quantuva would be straightforward.
