Etymology
the word 'rivalrous' is built upon the core noun 'rival', which originates from the latin rivalis, meaning a person sharing the same stream (rivus). this literal sense of sharing a common, and often contested, resource naturally evolved to signify competition and opposition. the suffix '-ous', from latin -osus, denotes 'full of' or 'characterized by'. therefore, 'rivalrous' literally means 'full of rivalry', directly extending the concept of competition to describe behaviors, relationships, or, in economic terms, the nature of goods where one person's use excludes another's.
