What is poetic language? how is it different from poetry?

I think that poetic language is a type of language that you can use to describe things. i think that poetic language is mostly used in books and novels since the language is very descriptive and sentimental and it is language that can be used in poetry but it is not a poem, it is just very descriptive and gives sensory details in a novel. i think that poetic language comes from poetry, like, the kind of language used in poems is being used in other areas of literature.
