Final answer:
Anaphora is the term for the repetition of a word or phrase at the beginning of successive clauses in literature to evoke emotion or emphasize a point.
Step-by-step explanation:
The term for the repetition of a word or phrase at the beginning of successive clauses or sentences in a literary work that adds emotion is anaphora. This device is employed by writers to emphasize a particular point or to evoke emotion within the reader. Unlike alliteration, which refers to the repetition of initial consonant sounds, or assonance, which is the repetition of vowel sounds within words, anaphora specifically involves the repeated use of words or phrases at the beginning of sentences or clauses. A well-known example of anaphora is Martin Luther King Jr.'s speech wherein he uses "I have a dream" at the beginning of several sentences to emphasize his vision for equality and justice.
