This kind of combat most commonly takes place on a battlefield or warzone on the ground (called a combat zone). Aerial combat involves fighting in the air among air forces. Hand-to-hand combat involves close fighting, often literally with one’s hands. Combat is often used as a modifier (adjective) in terms that refer to things related to or involving combat, such as combat training, combat medic, combat fatigue, and combat boots. Combat is sometimes used more broadly or figuratively to refer to active conflict between two people or groups, as in The two corporations are preparing to do combat in the courtroom. The term verbal combat refers to fighting with words. Combat is also commonly used as a verb meaning to oppose or work to defeat. It’s especially used when the thing to be defeated is intangible or abstract, as in We need to combat climate change or Our organization works to combat poverty. The figurative senses of the verbs fight and battle are close synonyms of this sense of combat. The sides engaging in combat can be called combatants. The adjective combative means inclined to fight.

Etymology

Origin of combat

First recorded in 1535–45; from Middle French combat (noun), combattre (verb), from Late Latin combattere, from Latin com- com- + Late Latin battere, from Latin battuere “to strike, beat”

Explanation

Combat is fighting between two groups of armed forces. When you engage in combat, typically this means you engage in fighting that involves weapons. Combat comes from the Latin com- meaning "together with" and battere meaning "to fight." Combat can be used as a modifier; for example, a combat zone is an area where fighting is taking place. The word combat can also be used to refer to the action of fighting against something to prevent it. An after-school program for kids is working to combat the issue of street violence by creating a safe space where kids can go as an alternative.
