Where does tagger come from?
“Tagger” was formed in English by adding the agent suffix “-er” to “tag,” producing a word for a person or device that performs the action of tagging. “Tag” itself has long been used for a small label attached to an object and, by extension, for a piece of identifying information attached to text, images, or digital records. The compound-like derivation reflects the English convention of naming an action performer with “-er.”
