Etymology
The word "effectiveness" is a layered construction built upon the Latin root effectus, meaning "accomplishment" or "performance," which itself derives from the verb efficere ("to work out, accomplish"). The suffix -ive was added in Middle English, borrowed from Latin -ivus, to form the adjective "effective," meaning "having the power to produce a result." Finally, the native English suffix -ness, denoting a state or quality, was appended to create the abstract noun. Thus, the term's logical journey traces from the concrete act of accomplishing something (effect) to describing the capacity for accomplishment (effective), and finally to the abstract quality of that capacity (effectiveness).
