Did you know?

When validate first entered the language in the mid-17th century, its meaning was tied fast to its close relative, the adjective valid: to validate something, such as a marriage or treaty, was to make it legally valid. This meaning is still current, but the word is now used in nonlegal and informal contexts.

If someone's claims cannot be validated, those claims cannot be confirmed.
