"omission of conjunctions," 1580s, from Latin, from Greek asyndeton, neuter of asyndetos "unconnected," from a-, privative prefix (see a- (3)), + syndetos, from syndein "to bind together," from syn- "together" + dein "to bind," related to desmos "band," from PIE *de- "to bind."
the omission of the conjunctions that ordinarily join coordinate words or clauses, as in the phrase "I came, I saw, I conquered" or in Matthew Arnold's poem The Scholar Gipsy:Thou hast not lived, why should'st thou perish, so?Thou hadst one aim, one business, one desire; Else wert thou long since numbered with the dead
