When you take your new love to meet your parents, you hope that they approve of your choice in partners, but when your date starts eating with his hands at dinner, chances are pretty slim.
Approve was first used like to mean "prove" or "show"––think, "The proof is in the pudding." Now, approve means to officially agree. You might need the principal to sign off on, or approve, any purchase of new materials for the classroom. Congress can also approve a bill or budget in this way. It’s important to remember that, like apple and appropriate, approve is spelled with a double “p.”
