"For, what with my whole world-wide wandering,..."
See in text (Childe Roland to the Dark Tower Came)
The repetition of the initial w sound is a marked example of both alliteration and consonance, or the internal rhyming of consonant sounds. As is the case here, alliteration and consonance are used to emphasize passages in prose and verse, either to convey an effect or anchor the line in readers’ minds. In this passage, the w sound forces readers to slow down, drawing out the phrase in such a way that mimics the duration of the speaker’s quest.
