Etymology

Origin of certificate

1375–1425; late Middle English certificat < Medieval Latin certificātum, noun use of neuter of certificātus certified (past participle of certificāre ), equivalent to certific- ( see certify) + -ātus -ate 1

Explanation

A certificate is a paper or document that proves some fact. Your most prized possession might be the certificate you got when you became a black belt in karate. Your fastidious friend might need to check the health inspection certificate before she'll agree to eat in a restaurant, and you'll need a copy of your birth certificate before you can apply for a passport. A certificate certifies or documents the fact that you are who you say you are, that you're licensed to drive, or authorized to practice dentistry, for example. You can trace the word certificate back to the Latin certus, "sure, fixed, settled."
