This paper addresses a frustrating crux found in a passage of the textus receptus (the 1623 First Folio, the only substantive text for Errors). Editors have tried to make sense of the conundrum of this passage by applying emendations. Attention to the rhetorical strategies employed by the Author and to the surrounding context of discourse can throw some light on the intended meaning: equivocation is one of the most effective rhetorical devices available for comedy and rhetorical figures pertaining to the field of aequivocatio are at the grass-roots of this drama. Punning offers a solution to the hermeneutical puzzle of the passage by helping to unravel the crux: it participates in a compositional strategy that encompasses the entire play. Quibbling and double entendre, far from being superficial expedients to elicit humour, here must be understood as constituting a fundamental productive means to develop the play’s rationale and to flesh-out the personality of its characters.
