exacting

The adjective 'exacting' originates from the verb 'exact,' which entered English in the late 15th century from Latin exactus, the past participle of exigere meaning "to demand, require, enforce, or drive out." This Latin verb is a compound of ex- ("out") and agere ("to drive, lead, do"). The literal sense was "to drive out," which evolved to "to demand (by driving out)," implying a forceful requirement. The '-ing' suffix was added to form the participial adjective, which describes the nature of someone or something that demands great precision, effort, or compliance, thus "driving out" the required standard from others. The modern meaning retains this core logic of rigorously demanding and leaving no room for error.
