Permission slips are documents that are used to give permission for a person or group to do something. The term PERMISSION SLIP can be broken down into three words: PASS, NOTE, and RELEASE. PASS is a four letter word meaning to move forward or to be accepted. NOTE is also a four letter word meaning to take notice of or to remember. RELEASE is a seven letter word meaning to set free or to allow. Together, these three words form the phrase PERMISSION SLIP, which is a document that grants permission for a person or group to do something.
