The word "tag" dates back to the late 14th century and can be traced back to the Old Norse word "tagg", meaning "pointed piece" or "protuberance". Over time, the concept of "tagging on" has emerged, referring to the act of attaching or adding something to an existing item or situation. Therefore, "tag on" is an extension of the original meaning of "tag" and signifies the action of appending or adding on.
