aggression
[C/U] Both
This word carries a heavy weight of intent and force. It describes a proactive push toward conflict rather than a reactive defense. In a psychological sense, it suggests a drive to dominate or harm, often linked to anger or instinctual territoriality. In geopolitical terms, it implies a violation of boundaries and a breach of peace. While "violence" describes the act of harm, "aggression" describes the spirit and the initiative behind the attack, marking the transition from tension to active hostility.
Uncountable when describing a general personality trait or a state of hostility. Countable when referring to a specific instance or a formal act of war.
