"Restricted", "constrained", "confined", "circumscribed" and "bounded" are some of the synonyms that can be used in place of "limited to". These words are often used to indicate a limitation or restriction in the scope or extent of something. For instance, if an individual is restricted to work within a specific domain or a certain set of rules, then he or she may be considered constrained in their work. Similarly, when a company is confined to a specific market or location, it is circumscribed in its reach. Employing synonyms such as these can add depth and nuance to one's language, and help to convey a more precise and nuanced meaning.
