Limitlessly; indefinitely into the future; endlessly; describing how something goes on forever: Jonathan Swift, an English satirist born in Ireland (1667-1745), wrote: "So, naturalists observe, a flea hath smaller fleas that on him prey, and these have smaller still to bite ‘em, and so proceed ad infinitum."

The term is often used interchangeably with ad nauseam and the original Latin sense is "beyond limits".
