Pronounced not unlike the quacking of a duck, gwork is a wonderful word handed down from the language of the Cewri (the "giants" of Welsh folklore).  In a nutshell, it means "struggling to the last."  It implies "to enjoy fighting, and to be fond too of what you're fighting for, or of what you're fighting against. . . . [I]t means enjoying life to the end or at least fighting to enjoy life to the end."  It seems to declare in one breath "that you were glad to have lived and that you'd struggle to the last to feel you were glad, in fact fight to the last to feel it; to feel, I mean, that weak as you might be, that defeated as you might be, that humiliated as you might be, that feeble and ridiculous as you might be, and as much like a wounded insect as you might be, you still refused to curse life. . . . It means using the soul in us to fight and enjoy the universe at the same time.  And to achieve this trick we've got to feel the soul in us as if it were in some sort of way independent of the body, although not necessarily . . . capable of surviving the death of the body.  We've got to feel it as if it were an unconquerable generator of energy within us, as if it were a self-quickening pulse of power and force, like a bodiless living creature, a creature of an airy rather than of a fluid or fiery essence, but a creature we can feel . . . in our two hands, our two legs, our sex organs and all our senses" (John Cowper Powys, Porius, pp. 569-70).
