The surname Amis is of English origin, and is generally considered to be derived from the Old French word "ami," meaning "friend" or "lover." It could have originated as a nickname applied to someone of a friendly or amorous disposition. In some instances, the name may also be a shortened form of a Germanic personal name beginning with the element "amal," meaning "work" or "activity."
The surname Amis can be found predominantly in England, and over time, has spread to other English-speaking countries, including the United States, Canada, and Australia, through migration. Variations in spelling, such as Amiss, are also found.
