Illegitimate vs. Illegal: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on October 27, 2023
Illegitimate refers to something that is not authorized or recognized by law or societal norms, while Illegal explicitly means a violation of the law. Both terms imply lack of validity but operate in different realms.

Key Differences
Illegitimate generally means lacking legality, validity, or recognition. It is a term that could be applied to a wide range of subjects, from children born out of wedlock to an illegitimate claim. Illegal, however, specifically implies a breach of law. While both terms are often used in a legal context, Illegitimate can extend beyond legal boundaries into social or moral spheres.

From a grammatical standpoint, both Illegitimate and Illegal are adjectives. However, Illegal is often used in contexts directly involving law enforcement or the judiciary. For instance, "illegal drugs" refers to substances prohibited by law. In contrast, "illegitimate means" could refer to methods that are not only against the law but may also violate ethical or societal norms.

Illegitimate and Illegal can sometimes be used interchangeably, but they have nuanced differences. For example, a business action can be illegitimate if it violates ethical norms, even if no law specifically forbids it. On the other hand, an action is illegal only if it violates a specific law. Therefore, while all illegal activities are essentially illegitimate, not all illegitimate activities are necessarily illegal.

Another key difference lies in their usage in everyday language. The term Illegal is often far more straightforward, implicating a clear breach of established laws. Illegitimate, however, can be more subjective, often requiring context for clarification. For instance, calling a government "illegitimate" may require examination of legal, ethical, and social considerations, while declaring an action "illegal" typically only involves the legal aspect.
