Amphibology
AMPHIBOLOGY, or AMPHIBOLY , in logic, a verbal fallacy arising from ambiguity in the grammatical structure of a sentence (Aristot., Organon,Soph., El., chap. iv.). It occurs frequently in poetry, owing to the alteration for metrical reasons of the natural order of words; Jevons quotes as an example Shakespeare, Henry VI.: "The duke yet lives that Henry shall depose."
