Did You Know?
The word average came into English from Middle French avarie, a derivative of an Arabic word meaning “damaged merchandise.” Avarie originally meant damage sustained by a ship or its cargo, but came to mean the expenses of such damage. When the English borrowed the word, they altered it to conform to the pattern of words ending in age. When a ship or its cargo was damaged at sea, the owners or insurers shared the expense, or average. An averageadjuster determined a division of costs among them. An average then became any equal distribution or division, like the determination of an arithmetic mean. Soon the arithmetic mean itself was called an average. Now the word may be applied to any mean or middle value or level.
Origin and Etymology of average
from earlier average proportionally distributed charge for damage at sea, modification of Medieval French avarie damage to ship or cargo, from Old Italian avaria, from Arabic ʽawārīya damaged merchandise
