Unentitled may convey a sense of not being qualified or deserving, and there are several synonyms that can express a similar idea. One possible alternative is "disqualified," which suggests that someone lacks the necessary credentials or meets some specific criteria. "Unworthy" implies a lack of merit or value, while "undeserving" suggests that someone does not deserve something due to their behavior or actions. Additionally, "ineligible" suggests that someone is incapable of receiving something due to certain restrictions or disqualifications. Ultimately, the choice of synonym depends on the context and intended meaning, but all of these words convey a sense of not being entitled to something.
