Anaphora is the succession of clauses or sentences starting with the same word(s).

The same word or phrase is used to begin successive clauses or sentences. Thus, the reader's / listener's attention is drawn directly to the message of the sentence.

Example:

"A man without ambition is dead. A man with ambition but no love is dead. A man with ambition and love for his blessings here on earth is ever so alive." (Pearl Bailey)

Anaphora is often used in conjunction with parallelism or climax.
