Which term best describes someone who is bad-tempered, argumentative, and uncooperative?

The term "cantankerous" accurately describes someone who is bad-tempered, argumentative, and uncooperative. This word is commonly used to characterize individuals who exhibit a quarrelsome nature and are often difficult to deal with due to their irritability and tendency to engage in disputes. Such individuals may frequently express dissatisfaction with others or situations, reinforcing a negative and contentious atmosphere.

In contrast, "affable" refers to someone who is friendly and easy to talk to, which does not align with the characteristics of being bad-tempered or uncooperative. "Docile" describes a person who is easily managed or submissive, which is opposite to the idea of being argumentative or uncooperative. Finally, "cooperative" implies a willingness to work together and engage positively with others, which directly contradicts the qualities of being cantankerous. Therefore, "cantankerous" is the most suitable term for someone with the described traits.
