In rhetoric, parechesis () is the repetition of the same sound in several words in close succession.
An example of a parechesis is: "He persuades the Pithian ()." Hermogenes of Tarsus discusses parechesis in his work On the invention of arguments (àõÃÂá½¶ Ã栫ÂÃÂÃÂÃÂõÃÂÃÂ). Alliteration (initial rhyme) is a special case of parechesis.
It is related to paronomasia.
