Average

Average, av′ėr-āj, n. the mean value or quantity of a number of values or quantities: any expense incurred beyond the freight, payable by the owner of the goods shipped, as in the phrase Petty average: any loss or damage to ship or cargo from unavoidable accidental causes—Particular average. Again, General average is the apportionment of loss caused by measures taken for the ship's safety, as cutting away the masts, throwing overboard cargo, accepting towage, or the like.—adj. containing a mean value: ordinary.—v.t. to fix an average.—v.i. to exist in, or form, a mean quantity. [Dr Murray says the word first appears about 1500 in connection with the maritime trade of the Mediterranean (Fr. avarie, Sp. averia, It. avaria); probably averia is a derivative of It. avere (O. Fr. aveir), goods, the original sense being a 'charge on property or goods.' The It. avere and O. Fr. aveir meant goods, substance, cattle—L. habēre, to have. The Old Eng. aver in the same sense is obsolete, but in Scotland aver still means an old horse.]
