Summary

In Latin ius (like droit in French, diritto in Italian, Recht in German) can mean a whole body of normative rules, a legal order, as well as “right,” in the many senses of the English word. Early in the last century, Wesley Newcomb Hohfeld proposed that English speakers resolve the ambiguity about the meaning of “right,” at least in precise legal language, by using the word “right” only where there was a correlative “duty” in another or others. If there was no correlative duty, but simply an absence of right in someone else (a “no-right”), Hohfeld preferred to say that the subject had a “privilege.” Hohfeld also proposed four other “fundamental legal categories”: “power” (another word that is sometimes encompassed in “right”), “immunity” (also sometimes encompassed in “right”), “liability,” and “disability,” categories that referred to the subject’s ability or lack thereof to change the first set of categories.
