An expression granting permission; an indication of agreement with a proposal; an acknowledgement that a person, thing, or event meets requirements.

In plain English: Approval is when someone agrees with you and says what you did was good.
"The teacher gave her approval when she saw the finished painting."
Usage: Approval refers to the act of agreeing with a plan or confirming that something meets necessary standards, such as giving permission for a project to proceed. Use it to describe a positive endorsement rather than mere observation or silence.
The word approval comes from the verb approve with the suffix -al added to form a noun. It entered English as a direct construction of these two parts to describe the act of agreeing or consenting.
