Appropriateness for the occasion can be described as having the right thing in the right place at the right time. This term can be broken down into three parts: NONCE, EVENT, and APT. NONCE is a word used to describe something that is used or done only once. An EVENT is an occurrence or happening, usually of some importance. APT is an adjective meaning suitable or appropriate for a particular person, purpose, or situation. Together, these three words form a phrase that describes the idea of having the right thing in the right place at the right time.
