What does validate mean?
To validate something is to establish or confirm that it is valid, sound, genuine, or acceptable. The word is used when checking data against reliable standards, confirming the legitimacy of a document or identity, testing whether a program or input meets required conditions, or formally approving an arrangement. “Validate” often implies more authority or formality than “check”: a laboratory may validate a result, a security system may validate credentials, and a regulator may validate a submission. The term also appears in discussions of research, where replicated evidence can validate a hypothesis, although it does not necessarily prove it beyond all doubt. In computing, “validation” commonly refers to checking whether data or a system satisfies rules, formats, or constraints. Related forms include “valid,” “validity,” “validator,” and the opposite “invalidate.” The verb is standard in both British and American English and is especially common in scientific, legal, administrative, and technical registers.

At its root, validate means “to make strong”: its Latin ancestor valued strength, soundness, and worth long before the word became associated with forms and approval processes.

Where does validate come from?
The word entered English in the early 17th century through French and Latin usage. It ultimately derives from Latin validus, meaning “strong, sound, or effective,” which was based on valere, “to be strong” or “to be worth.” The idea of worth developed into the modern sense of validity, while the same broad Latin root also produced words such as value and valid.
