Offer and acceptance
two components of agreement

Offer and acceptance are generally recognized as essential requirements for the formation of a contract (together with other requirements such as consideration and legal capacity). Analysis of their operation is a traditional approach in contract law. This classical approach to contract formation has been modified by developments in the law of estoppel, misleading conduct, misrepresentation, unjust enrichment, and power of acceptance.
Offer
Definition
Guenter Treitel defines an offer as "an expression of willingness to contract on certain terms, made with the intention that it shall become binding as soon as it is accepted by the person to whom it is addressed", the "offeree". An offer is a statement of the terms on which the offeror is willing to be bound. The same emphasis on "willingness" is expressed in the Restatement (Second) of Contracts: "an offer is the manifestation of willingness to enter into a bargain, so made as to justify another person in understanding that his assent to that bargain is invited and will conclude it".
The expression of an offer may take different forms, and which form is acceptable varies by jurisdiction. Offers may be presented in a letter, newspaper advertisement, fax, email verbally or even conduct, as long as it communicates the basis on which the offeror is prepared to contract. Traditionally the common law treated advertisements as being unable to contain offers, but this view is considered less forceful in jurisdictions today.
Whether the two parties have reached agreement on the terms or whether a valid offer has been made is a legal question.
Begin with the source’s own compact description: “Offer and acceptance” is two components of agreement. The dossier treats that line as a proposition to test through Offer, acceptance and components, not as a finished interpretation.
Why this record matters
The phrase “two components of agreement” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 3, 2026. The linked authority identifier is Q1193004. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
