14. n. =Syn.6. Wit, Humor. In writers down to the time of Pope wit generally meant the serious kind of wit.
15. n. In more recent use wit in the singular generally implies comic wit; in that sense it is different from humor. One principal difference is that wit always lies in some form of words, while humor may be expressed by manner, as a smile, a grimace, an attitude. Underlying this is the fact, consistent with the original meaning of the words, that humor goes more deeply into the nature of the thought, while wit catches pleasing but occult or farfetched resemblances between things really unlike: a good pun shows wit; Iiving's “History of New York” is a piece of sustained humor, the humor lying in the portrayal of character, the nature of the incidents, etc. Again, “Wit may, I think, be regarded as a purely intellectual process, while humor is a sense of the ridiculous controlled by feeling, and coexistent often with the gentlest and deepest pathos” (H. Reed, Lects. on Eng. Lit., xi. 357). Hence humor is always kind, while wit may be unkind in the extreme: Swift's “Travels of Gulliver” is much too severe a satire to be called a work of humor. It is essential to the effect of wit that the form in which it is expressed should be brief; humor may be heightened in its effect by expansion into full forms of statement, description, etc Wit more often than humor depends upon passing circumstances for its effect.
16. n. One who has discernment, reason, or judgment; a person of acute perception; especially, one who detects between associated ideas the finer resemblances or contrasts which give pleasure or enjoyment to the mind, and who gives expression to these for the entertainment of others; often, a person who has a keen perception of the incongruous or ludicrous, and uses it for the amusement and frequently at the expense of others.
17. To play the wit; be witty: with an indefinite it.
18. See wite.
