It's impossible to give an exact number of poems he wrote for a few reasons:
* Definitions of "poem": What counts as a poem? Does it include short verses, drafts, or just published works?
* Lost or unpublished works: Some of Wordsworth's work may be lost or never published.
* Ongoing research: Scholars continue to discover and study his writings.
However, we can say that William Wordsworth was a prolific writer, and his body of work is extensive. His most famous poems include:
* "Tintern Abbey"
* "I Wandered Lonely as a Cloud" (also known as "Daffodils")
* "Ode: Intimations of Immortality from Recollections of Early Childhood"
* "She Dwelt Among the Untrodden Ways"
