aprosdoketon
A figure of speech where an expected word in an idiom is replaced unexpectedly by an unusual one, as in Rome wasn't built in a teacup.
Is the poet saying "I do not chance on even a slight respect from you" or "I chance on a good amount of respect from you," a meaning which effectively postpones the aprosdoketon to the final line[?]
Any surprising use or interpretation of language.
In later restagings of the Thesmophoriazusae, as in the 1959 Frogs, Euripides made his appearance driving a motorcycle. This scenic aprosdoketon was, of course, an ingenious verbal and visual pun on the word mechane and its different meanings in ancient and modern Greek: "stage crane" and "motorbike," respectively.
Where it comes from
