Alliteration is the repetition of initial consonant sounds in closely placed words within a line or phrase. In the line from Agostinho Neto's The Grieved Lands, the b sound recurs prominently in "by baobabs" and "balances," while the d sound links "Decked" and "dances." This clustering of the same initial consonant across multiple words in a single line is the hallmark of alliteration.

The other literary devices differ in specific ways. Assonance involves the repetition of vowel sounds within words (for example, the long o in "go slow over the road"), not consonant sounds at the start. Consonance is the repetition of consonant sounds at the end or in the middle of words, not at the beginning. Onomatopoeia refers to words that phonetically imitate the sounds they describe, such as "buzz" or "hiss," which is not what happens here.

When identifying alliteration, look for two or more words in close proximity that begin with the same consonant sound. In this line, the repeated b and d sounds at the start of successive words make alliteration the dominant device.
