non disclosure agreement

This term is primarily used in legal, corporate, and professional contexts to protect intellectual property and trade secrets. It carries a formal, restrictive tone, signaling a high level of trust and legal obligation between the signing parties.

In common business parlance, this phrase is frequently shortened to the acronym NDA. While the full term is used in the actual contract document, the acronym is the standard way to refer to the concept in emails, meetings, and casual professional conversation.
