What does unjustified mean?
Unjustified is an adjective meaning that something lacks a sufficient reason, evidence, or moral basis. It is commonly used to describe claims, criticism, reactions, or actions that are regarded as excessive, unsupported, or unwarranted: saying that a concern is unjustified implies that no reasonable basis exists for it. The word does not merely mean false or disagreeable; it distinguishes an unsupported response from a justified one, though in practice it can carry a strongly critical tone. In legal and institutional contexts, unjustified may describe force, interference, or treatment that lacks legitimate grounds. Because it is evaluative, it should be used where the absence of a reason can be identified, rather than merely to dismiss an unpopular opinion. Its usefulness lies in making the claim that a response has crossed from reasonable concern into unreasoned or excessive action.

Where does unjustified come from?
Unjustified was formed in English with the prefix un- and the past participle justified, meaning “made right or shown to be reasonable.” The related words justify, justification, and justice descend through Old French and Latin from Latin justus, meaning “just” or “upright.” The prefix un- reverses the sense of justified, producing a word that denotes something lacking a valid reason or basis.
