artistic/poetic licence

artistic license

1. Intentional violations of or deviations from traditional forms, standards, or syntax by a writer in order to achieve a particular effect. Don't get hung up on adhering too strictly to iambic pentameter—you can use a bit of artistic license if it means preserving the meaning and rhythm you want. Any two-bit poet can string together a jumble of words and call it artistic license.
2. Minor changes to or misrepresentations of facts or history in the name of art or for the sake of an agenda. People complain about minor inaccuracies in historical dramas, but honestly they wouldn't be able to make the movies marketable without using a little artistic license.
