A paraprosdokian is a
figure of speech in which the latter part of a sentence or phrase is surprising
or unexpected in a way that causes the reader or listener to re-frame or
re-interpret the first part.
A good example, where
the word “right” changes meaning as the sentence is completed, is: "War doesn’t determine who is right only who
is left."
Another example - Silence is golden;
duct tape is silver.
