Etymology
the word 'combatant' entered english in the late 15th century from old french, where 'combatant' was the present participle of 'combatre', meaning 'to fight'. the old french term itself derived from the late latin verb 'combattere', a compound of the latin intensive prefix 'com-' (meaning 'together, with') and 'battuere' (meaning 'to beat'). the suffix '-ant', originating from the latin present participle ending '-antem', denotes an agent or someone performing an action. thus, the literal construction 'one who fights together' or 'one engaged in beating/fighting' evolved into its modern, more abstract meanings, applicable to both a person who fights in armed conflict and the state of being ready for combat.
