Keatsian describes poetry or language that recalls John Keats's style: richly sensory, musical, and often drawn toward beauty, nature, longing, and the ache of mortality. A Keatsian poem may linger over vivid images and emotional atmosphere rather than argument or plain statement.
The word can also suggest the Romantic qualities associated with Keats, especially deep feeling, sensuous detail, and a willingness to dwell in uncertainty or desire.
Example
A Keatsian autumn dusk lay over the hill,
where pears shone gold and the last bees were still;
the leaves, like embers, trembled in the air,
and beauty felt as brief as a prayer.
