“_This girl reminds me of Dreyfus. The army does not believe in her innocence._” The word innocence, whose double meaning furnishes the basis of the witticism, has in one connection the customary meaning which is the opposite of guilt or transgression, while in the other connection it has a sexual sense, the opposite of which is sexual experience. There are very many such examples of double meaning and in each one the point of the joke refers especially to a sexual sense. The group could be designated as “ambiguous.” _A good example to illustrate this is the story told of a wealthy but elderly gentleman who showed his devotion to a young actress by many lavish gifts. Being a respectable girl she took the first opportunity to discourage his attentions by telling him that her heart was already given to another man. “I never aspired as high as that,” was his polite answer._ If one compares this example of double-meaning-with-ambiguity with other examples one cannot help noticing a difference which is not altogether inconsequential to the technique. In the joke about “innocence” one meaning of the word is just as good for our understanding of it as the other. One can really not decide whether the sexual or non-sexual significance of the word is more applicable and more familiar. But it is different with the other example mentioned. Here the final sense of the words, “I never aspired as high as that,” is by far more obtrusive and covers and conceals, as it were, the sexual sense which could easily escape the unsuspecting person. In sharp contrast to this let us examine another example of double meaning in which there is no attempt made to veil its sexual significance—e.g., Heine’s characterization of a complaisant lady: “_She could pass (abschlagen) nothing except her water._” It sounds like an obscene joke and the wit in it is scarcely noticed.[28] But the peculiarity that both senses of the double meaning are not equally manifested can occur also in witticisms without sexual reference providing that one sense is more common or that it is preferred on account of its connection with the other parts of the sentence (e.g., _c’est le premier vol de l’aigle_). All these examples I propose to call double meaning with allusion. We have by this time become familiar with such a large number of different techniques of wit that I am afraid we may lose sight of them. Let us, therefore, attempt to make a summary. I. CONDENSATION (a) with mixed word-formation. (b) with modification. II. THE APPLICATION OF THE SAME MATERIAL (c) The whole and the part. (d) Change of order. (e) Slight modification. (f) The same words used in their full or colorless sense. III. DOUBLE MEANING (g) Name and verbal significance. (h) Metaphorical and verbal meaning. (i) True double meaning (play on words). (j) Ambiguous meaning. (k) Double meaning with allusion.
