costing

The word 'costing' is built upon the noun 'cost', which entered English via Old French from the Latin verb constare, meaning "to stand together, to stand at (a price)". The core idea is of a price that is fixed or settled. The addition of the Germanic suffix '-ing', a prolific noun-forming element in English, transforms the base word into a term specifically denoting the process or system of determining and analyzing expenses. This evolution from a simple price to a formalized accounting procedure reflects the development of complex commercial and industrial systems. Thus, 'costing' logically represents the systematic application (the '-ing' action) to the fundamental concept of expense ('cost').

Structure: cost (price, expense) + ing (noun-forming suffix) cost: From Middle English, from Old French cost, from Latin constare ("to stand at, to cost"). The functional role is the core semantic root meaning "expense, price". ing: From Old English -ing, -ung, a suffix forming nouns from verbs, indicating an action, process, or result. Its functional role is to nominalize the verb 'cost', turning it into a noun for the process or result.
