What does 'incursion' mean?

The term 'incursion' refers specifically to an entry into an area that is not owned or rightfully belonging to the entrants. This definition captures the essence of an incursion, often implying a sense of intrusion or aggression. In various contexts, particularly in military or law enforcement terminology, it denotes an illegal or forceful entry into a territory, suggesting that the entrants do not have permission or legal right to access that area.

This meaning differentiates 'incursion' from terms that might imply legal entry or friendly visitation. For instance, a peaceful entrance or friendly visitation suggests consent and mutual agreement, while an entry into a rightful area implies that the entrants are acting within their legal boundaries. Therefore, the definition provided aligns most closely with the idea of an incursion being an unauthorized or intrusive entry into someone else's territory.
