The word "sur-pass" implies the act of exceeding or going beyond a limit or expectation. Its antonyms, therefore, would be words that denote the opposite, such as "under-perform," "fall short," "lag behind," "miss the mark," or "fail to meet expectations." These words imply that the performance or achievement is not up to the mark or the level expected, thus lacking the quality or quantity needed to surpass others. While "sur-pass" is often associated with success and excellence, its antonyms indicate a failure or a less favorable outcome. Hence, paying attention to the antonyms of "sur-pass" can give a useful perspective on evaluating one's performance and setting expectations.
