An offer (or a “proposal”) is not defined by statute. It is generally understood as denoting the expression, by words or conduct, of a willingness to enter into a legally binding contract as soon as it has been accepted, usually, by a return promise or an act on the part of the person (the offeree), to whom it is so addressed.

An acceptance, in relation to an offer, is a final and unqualified expression of assent to the terms of the offer.

Offer, followed by acceptance, is an “agreement”, if an agreement is enforceable by law, it is a “contract”.
