Certificate
Written Proof
noun
Remember how 証明 means "proof"? Well, when you write the proof down on something, you have a certificate.
This can be used for different kinds of written proof, like a 卒業証明書 (graduation certificate), 身分証明書 (personal ID), and more.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well. Knowing 証明's reading will also be helpful.
