Ambiguity
This means ‘more than one possible meaning’. The rules of grammar exist to allow a structure of words to be created that has a single clear meaning, i.e. to be unambiguous. Here is an ungrammatical sentence that was an actual warning notice at the bottom of an escalator: ‘Dogs must be carried on the escalator’. What does this mean? Are you allowed to ride on the escalator without a dog in your arms?
In literature, writers often create a sense of ambiguity on purpose. This can be done through the use of irony. It has the effect of engaging the reader more closely with the text and is one thing that can lead to various and different interpretations of the text.
