Other forms: poetic licenses
The term poetic license describes the freedom an artist or writer has to change details, distort facts, or ignore the usual rules — especially if the art they produce is better as a result.
When a novelist or a poet twists facts, invents words, or disregards grammar rules because it makes for a more satisfying story or a lovelier poem, they use poetic license. Another example of this is when a cartoonist, using poetic license, draws a version of a real person that doesn't look exactly like them, but exaggerates some physical characteristics. A filmmaker also does this when she changes the facts in a true story to make a more interesting movie.
