The compound "war-making" is a transparent combination of two robust Germanic elements. "War" entered English via Old Norman French, replacing the native Old English 'guþ', and carries the core sense of large-scale, organized armed conflict. "Making," derived from the ubiquitous Old English verb 'macian', signifies the act of creating or doing. When fused, the term follows a classic English compounding pattern, literally meaning "the making of war." This logical construction directly names the process, shifting from the abstract concept of "war" to the concrete activities—planning, mobilizing, fighting—that constitute its execution. Its modern usage encompasses both the factual description of engaging in hostilities and the attributive description of capabilities or institutions dedicated to that purpose.

Structure: war (armed conflict) + making (the act of creating or doing) - war: From Old English 'werre' (confusion, strife, armed conflict), from a Germanic base, ultimately of uncertain origin. Functions as the core noun root specifying the domain of action. - making: From Old English 'macian' (to make, construct, do). The suffix '-ing' forms a gerund/noun from the verb 'make', indicating the action or process. In this compound, it functions as a deverbal noun meaning "the act of doing."
