The term "beat off" typically refers to the action of defeating or warding off something or someone. There are several antonyms for the phrase, including "yield," "surrender," and "submit." In such cases, instead of beating off an opponent or threat, one would simply give in or acquiesce. Other antonyms include "collaborate," "consent," and "cooperate," which suggest a willingness to work together and find common ground. Alternatively, one could "embrace," "accept," or "welcome" a challenge or opportunity, rather than attempting to beat it off. In all cases, the antonyms for "beat off" imply a more peaceful and collaborative approach to problem-solving.
