Did you know?

The Old Norse word for a partner, felagi, means literally “one who puts down property.” Such people were those who laid together their property for some common purpose. Old English borrowed felagi from Old Norse and called a partner a feolaga. This word has come down to us, through several centuries and the development of a number of senses, as modern English fellow. Perhaps its most common use today is its very general one, in which it is applied to any boy or man.
