The object of this article is not to add one more hypothesis to the many others that have at various times been advanced to explain the origin of the Latin vī -Perfect, but rather to call attention to an old and neglected explanation which seems to the writer so simple and obviously superior to all the vague guesses which are apparently enjoying much greater favor, that it is a source of amazement, e.g. that Stolz-Leumann, Lat. Gram. 335, do not even mention the same in their extensive enumeration of theories and authorities.
Walter Petersen (Sat,) studied this question.
