Both poems are similar because they are both about nature and are also presented in a sad tone at first.
“I wandered lonely as a cloud” is a lyrical poem and it depicts Wordsworth’s response to nature’s beauty while the haiku by Basho represents the imagery of spring day.
Their structural difference is that the haiku only has three lines with 5, 7, 5 syllables each line while “I wander lonely as a cloud” has a stanza with six lines in iambic tetrameter.
