Acceptance of goods

What does Acceptance of goods mean in American Law?

The definition of Acceptance of goods in the law of the United States, as defined by the lexicographer Arthur Leff in his legal dictionary is:

In the law of sales, the buyer’s “acceptance” of the goods may effect a loss of certain claims and defenses which he might otherwise have, e.g., that the goods did not conform to the specifications in the contract of sale. A great many commercial disputes involve whether the buyer has in the particular case “accepted” the goods, i.e., whether he has expressed, under conditions of sufficient knowledge and understanding, that he is content to receive the goods as fulfilling the seller’s obligation. The

U.C.C. addresses itself explicitly to what will constitute “acceptance of goods;” indeed, § 2-606 is so titled, and ensuing Code sections deal with other special problems involving such “acceptance.”
