Some synonyms include calming down, patching things up, resolving the conflict, settling the dispute, reconciling, coming to an agreement, burying the hatchet, making peace, and smoothing things over. These synonyms represent various methods of finding common ground, understanding each other's perspective, and finding a way to move forward without resentment or bitterness. It's important to remember that ending a quarrel takes effort and willingness from both parties, but ultimately, it leads to a healthier and happier relationship.
