Convergence denotes a comb-n of stylistic devices promoting the same idea, emotion or motive. Any type of expr. means will make sense styl-ly when treated as a part of a bigger unit, the context, or the whole text. It means that there is no immediate dependence between a cert. styl. device and a definite stylistic fun-n.
A stylistic device is not attached to this or that stylistic effect. Therefore a hyperbole, for ex., may provide any number of effects: tragic, comical, pathetic or grotesque. Inversion may give the narration a highly elevated tone or an ironic ring of parody.
This «chameleon» quality of a stylistic device enables the author to apply dif. devices for the same purpose. The use of more than one type of expr. means in close succession is a powerful technique to support the idea that carries paramount importance in the author's view. Such redundancy ensures the delivery of the message to the reader.
