The repetition of the same consonant sounds in a sequence of words, usually at the beginning of a word or stressed syllable: "descending dew drops"; "luscious lemons." Alliteration is based on the sounds of letters, rather than the spelling of words; for example, "keen" and "car" alliterate, but "car" and "cite" do not. Used sparingly, alliteration can intensify ideas by emphasizing key words, but when used too self-consciously, it can be distracting, even ridiculous, rather than effective. See also assonance, consonance.
