Alliteration
In language, alliteration is the repetition of a particular sound in the prominent lifts (or stressed syllables) of a series of words or phrases. Alliteration has developed largely through poetry, in which it more narrowly refers to the repetition of a consonant in any syllables that, according to the poem's meter, are stressed, as in James Thomson's verse "Come…dragging the lazy languid Line along".
