Joseph Addison,
Essays and Tales
“ Having pursued the history of a pun, from its original to its downfall, I shall here define it to be a conceit arising from the use of two words that agree in the sound, but differ in the sense. The only way, therefore, to try a piece of wit is to translate it into a different language. If it bears the test, you may pronounce it true; but if it vanishes in the experiment, you may conclude it to have been a pun. In short, one may say of a pun, as the countryman described his nightingale, that it is “vox et præterea nihil”—“a sound, and nothing but a sound.” ”
