Which term means to bicker or quarrel, often implying an argument?

The term "wrangle" is most accurately associated with the idea of bickering or quarreling, as it suggests a prolonged and often petty argument. When people wrangle, they engage in a back-and-forth dispute that typically lacks a serious or formal nature, often revolving around trivial issues. This aligns closely with the notion of bickering, which conveys a sense of ongoing disagreement that is more focused on the act of arguing rather than reaching a resolution.

In contrast, a "dispute" generally refers to a disagreement that might not necessarily carry the same connotation of bickering; it can encompass a broader range of disagreements, some of which could be civil or formal in nature. A "debate" involves structured argumentation and discussion, usually focusing on differing views regarding specific topics, and often aims at a reasoned conclusion rather than simply arguing for the sake of arguing. "Conflict" implies a more significant clash or struggle, often escalating into serious disagreement or violence, which is beyond the more trivial nature associated with bickering. Thus, "wrangle" captures the essence of light, often petty argumentation, making it the most suitable choice for the definition given in the question.
