Clear; definite; explicit; plain; direct; unmistakable; not dubious or ambiguous. Declared in terms; set forth in words. Directly and distinctly stated. Made known distinctly and explicitly, and not left to inference. Manifested by direct and appropriate language, as distinguished from that which is inferred from conduct. The word is usually contrasted with implied.
That which is express is laid out in words, such as an express WARRANTY, which is an oral or written affirmation from a seller to a buyer of goods that certain standards will be met. Such a warranty may include the promise that any defect which occurs during a certain specified time period will be remedied at the seller's expense. This is distinguishable from an IMPLIED WARRANTY, which is neither written nor based on any specific oral statement from seller to buyer but is implied through the sale itself. A common example is the implied warranty of merchantability, which implies that an item is fit for the usual purposes for which it was purchased.
Express authority is plainly or distinctly delegated power to an agent by a principal. For example, the owner of a store may expressly give employees the authority to accept deliveries in the owner's name.
