What term describes a hostile and aggressive attitude?

The term that best describes a hostile and aggressive attitude is "belligerent." This word originates from a Latin root meaning "to wage war," and is often used to characterize individuals or groups that display an inclination toward conflict, aggression, or hostility. Those exhibiting a belligerent attitude may be quick to engage in confrontations and often prefer to resolve disputes through force rather than dialogue or negotiation.

While "confrontational," "aggressive," and "antagonistic" may share similar meanings, belligerent emphasizes a readiness for war or violent hostility. Confrontational suggests a tendency to engage in disputes, but it does not necessarily imply an inherent aggression. Aggressive can refer to any type of forceful behavior and may not always encompass the same level of hostility implied by belligerent. Antagonistic indicates opposition or hostility, but it does not capture the same readiness for conflict that is central to being belligerent. Thus, belligerent is the most precise choice when specifically describing a hostile and aggressive attitude.
