Amphiboly

 Definition 

Also called Amphibology.

An amphiboly occurs when the construction of a sentence allows it to have two different meanings.

 Explanation

 Examples

The Oracle of Delphi told Croseus that if he pursued the war he would destroy a mighty kingdom. What the Oracle did not mention was that the kingdom he destroyed would be his own.

Save soap and waste paper.
