quámëa ("q")adj. "sick" (evidently = nauseous, cf. quámë and the verb quama-) (QL:76)
laiwasick, sickly, ill
laiwa adj. "sick, sickly, ill" (SLIW, VT45:28). Since Tolkien eventually decided that roots in sl- yield Quenya words in hl- (though this was pronounced l- in late Exilic Quenya), it may be that the spelling *hlaiwa is to be preferred.
