The popular phrase "burying the hatchet" is often used to signify an end to conflicts or arguments. However, not all situations may warrant such an action. Antonyms for burying the hatchet could include "holding a grudge" or "nursing resentment," indicating ongoing negative feelings. Another antonym could be "escalating tensions," implying a desire to continue the conflict or even make it worse. Alternatively, "never letting go" could suggest a refusal to move on or forgive, while "fanning the flames" indicates a willingness to provoke or exacerbate the problem. Ultimately, the opposite of burying the hatchet is to refuse to let go of past grievances, perpetuating discord instead of seeking resolution.
