The term used to depict the freedom of a poet with language is "poetic licence." It refers to the freedom that poets have to depart from the normal rules of language and grammar to create a desired effect in their writing.

It gives poets the flexibility to express themselves in their own unique style and to create a distinctive voice in their poetry.
