From Oscar Wilde's essay *The Decay of Lying* (1891). Select the word that fits the blank. "Mr. Henry James writes fiction as if it were a painful duty, and wastes upon mean motives and imperceptible 'points of view' his neat literary style, his felicitous phrases, his swift and ______ satire."

Wilde is listing what Henry James has *wasted* on petty subjects: a neat style, felicitous phrases, and *swift and ______* satire. The blank modifies *satire*, which by nature must be sharp; *swift* primes the reader to expect a partner word about *cutting quickness*. "Caustic" — burning, corrosive (literal sense); biting, sarcastic (figurative) — fits both the satirical register and the speed/sharpness pairing with *swift*. - "Tender" would describe gentle, affectionate writing — the opposite of satire. - "Clumsy" attacks the writing itself; Wilde is praising the style as wasted on the wrong subject, not faulting it. - "Weary" doesn't fit the *swift* pairing. *Caustic* derives from Greek *kaustikos*, *capable of burning* — the figurative sense (sharp criticism) preserves the burn.
