Etymology
The word 'discriminative' traces its lineage to the Latin verb 'cernere,' which fundamentally meant to sift or separate, a concept rooted in the physical act of distinguishing one thing from another. Through the frequentative form 'discriminare' (to divide, distinguish), the core idea evolved from physical separation to the mental act of making careful distinctions or judgments. The prefix 'dis-' intensifies this sense of separation, while the suffix '-ative' transforms the verbal action into an adjective, describing the inherent quality of being able to perceive or create differences. Thus, the modern abstract meaning—pertaining to the ability to recognize fine distinctions—logically extends from the ancient, concrete act of sifting and setting apart.
Analysis
Structure: dis (apart) + crimin (distinguish) + ative (adjective-forming suffix)
- dis: A Latin prefix meaning "apart," "asunder," or "in different directions." It functions as an intensifier or separator.
- crimin: Derived from the Latin verb 'cernere' (to sift, separate, decide), specifically from its frequentative form 'criminare' (to accuse, to make a judgment). In this word, it acts as the core root meaning "to distinguish."
- ative: A Latin-derived suffix (-ativus) used to form adjectives meaning "of, relating to, or tending to" the action of the verb.
