Polysyndeton

Polysyndeton is the use of several conjunctions in close succession, especially where some might be omitted (as in "he ran and jumped and laughed for joy"). It is a stylistic scheme used to achieve a variety of effects: it can increase the rhythm of prose, speed or slow its pace, convey solemnity or even ecstasy and childlike exuberance. In grammar, a polysyndetic coordination is a coordination in which all conjuncts are linked by coordinating conjunctions (usually and, but, or, nor in English).
