adj. (grammar) expressing intensity or emphasis
The word "intensive" originates from the Latin intendere ("to stretch toward, aim"), composed of in- ("into") and tendere ("to stretch"). The morpheme tens reflects the past participle stem of tendere, implying a focused or concentrated effort. The suffix -ive turns it into an adjective, describing something characterized by such effort. Over time, "intensive" evolved to denote high concentration in various contexts, from agriculture to linguistics.
