Explanation:

A nudum pactum in Latin literally means 'Bare or Naked Promise.' In common law, it refers to a promise that is not legally enforceable for want of consideration. An example of a nudum pactum would be an offer to sell something without a corresponding offer of value in exchange. While the offer may bind a person morally, since the offer has not been created with any consideration, it is gratuitous and treated as a unilateral contract. The offer is therefore revocable at any time by the offeror before acceptance by the offeree.
