What does legitimate mean?
Legitimate means lawful, valid, genuine, or justifiable according to the relevant rules, standards, or evidence. It is used for institutions and activities that are officially recognized, for arguments and concerns that are reasonable enough to deserve attention, and for objects or people whose status is real and proper. For example, a legitimate business is one that operates within the law, while a legitimate complaint is one that is based on genuine grounds. The adjective can carry a formal tone and is often used in public, legal, and administrative contexts. Although “legal” focuses specifically on what the law permits, “legitimate” has a broader meaning: something may be legitimate because it is authentic, appropriate, or morally justifiable, not merely because no law prohibits it.
Conforming to law or recognized rules and standards; valid, genuine, proper, or justifiable.
"The court recognized the claim as a legitimate legal issue."
The meaning varies by context: it may emphasize legality, authenticity, or the reasonableness of a demand or concern.
To make something legitimate by establishing or recognizing it as valid, proper, or justified.
"The new constitution helped legitimize the government."
This use is less common than the adjective and is especially associated with formal political and legal discussion.
The word legitimate comes from the Latin legitimus, meaning “lawful,” and still carries the idea of something being properly founded or justified.

Where does legitimate come from?
The adjective comes from the Latin legitimus, meaning “lawful” or “according to law,” from lex, legis, “law.” English borrowed the word in the 15th century, initially in legal and political contexts. Its later meanings developed from the idea of a person or institution being lawfully established and recognized, and from the sense of a claim being justified or reasonable. Related English forms include “legitimacy” and the verbs “legitimise” and “legitimize.”
