When someone does not deserve something, there are several synonyms that can be used to express the same feeling. "Unmerited," "undeserving," "unwarranted," and "unearned" are all commonly used synonyms for "not deserved." All of these words can be used to convey a sense of injustice or unfairness, as when someone receives a reward or recognition they did not earn. "Unjustified" and "unjustifiable" are also options for expressing the idea that something is not deserved. No matter which synonym is used, the implication is that someone has received something they did not earn or are otherwise undeserving of.
