Poetic Language

the totality of the characteristics of language as an instrument of artistic expression and an object of artistic perception; synonymous with artistic (literary) language. The term “poetic language” is sometimes applied to verse speech —that is, to literary language that follows the rules of verse. In a narrow sense, “poetic language” or “poetic speech” refers to the specific language of poetry before modern times (for example, ancient Icelandic and classical Persian poetry), which used a vocabulary, phraseology, and syntax that were rarely encountered in other kinds of speech.
