In the Preface to Lyrical Ballads (1800, 1802), William Wordsworth argued that poetry should use the language of common people rather than the artificial and highly ornamented diction typical of 18th-century poetry. His main points about poetic language include:
Use of Everyday Language – Poetry should be written in the natural speech of ordinary people, especially rural folk, as their language is more authentic and emotionally expressive.
Rejection of Poetic Diction – Wordsworth criticized the highly elaborate and artificial language used by earlier poets (like those of the Neoclassical tradition) and insisted that poetry should avoid unnecessary ornamentation.
Emphasis on Emotion and Simplicity – Poetry should arise from "emotion recollected in tranquility," and its language should be simple yet profound, capable of conveying deep feelings.
The Role of the Poet – The poet is "a man speaking to men," meaning that poetry should communicate directly with readers, without the barriers of complex or artificial diction.
The Connection Between Poetry and Truth – By using the language of real life, poetry becomes a more truthful and powerful medium of expression.
