Origin & History of “spider”

The spider is etymologically the ‘spinner’. Its name goes back to a primitive Old English *spinthron, a derivative of the verb spinnan ‘spin’. The inspiration is the same, and much more obvious, behind other Germanic words for ‘spider’, such as German spinne, Dutch spinner, Swedish spindel, and Danish spinder.
