This account of the verb forms in Plautus proceeds in the same direction as my earlier papers on noun, adjectival, and adverbial forms (Classical Review, July, December, 1902, July, 1903). I feel strongly that something is needed on Plautine forms that shall be more complete and accurate than anything that yet exists. The statements that one meets with, that this or that form is “common,” or “regular,” in Plautus, are frequently misleading, or even incorrect, and are usually unsatisfying. I do not think it is of much import whether a word occurs fifty times or fifty-five, but it often is important to know whether it occurs fifty times, or five, or once, or not at all.
