When describing actions or behaviors that are permitted within legal boundaries, the phrase "allowed by law" is often used. However, there are several alternative synonyms that can be used to express this same concept. For example, "lawful," "legal," "permissible," "authorized," and "licit" all convey the idea of being within the confines of the law. Other related phrases include "within legal limits," "not prohibited by law," and "in compliance with regulations." Whether writing about business practices, personal actions, or political policies, using a varied vocabulary can help make language more precise and engaging.
