WordNet records no synonym and no antonym for human right. It is the only member of its synset, which is common for technical, taxonomic and single-sense vocabulary — there is no other English word that means the same thing. The broader and narrower terms below are the useful relations in that case.
Counts are distinct word forms across every sense. A synonym that appears under three senses is counted once here and shown three times below, under each sense it belongs to.
(law) any basic right or freedom to which all human beings are entitled and in whose exercise a government may not interfere (including rights to life and liberty as well as freedom of thought and expression and equality before the law)
