polysyndeton

noun

1. (countable, rhetoric, uncountable)The use of many conjunctions to achieve an overwhelming effect in a sentence.

   “In Polysyndeton conjunctions flow, And every word its copulative will shew.”

   “[Hemingway] often employs a variety of polysyndeton—a frequent use of conjunctions, most notably “and”—linking elements in a sentence together in a way that implies all parts are of equal importance, while in fact one unit of the series may be much more significant than the others.”
