What does untagged mean?
Untagged describes something that bears no tag, label, or identifying marker. The word is especially common when discussing merchandise, files, records, specimens, and other items that might otherwise have a tag for identification, categorization, pricing, or tracking. In digital and administrative contexts, an untagged record may lack metadata or a status designation rather than merely a physical label. The term is also used as part of the verb untag, meaning to remove such a marker. Although untagged often implies that a category or identifying tag could have been added, it does not mean that the item is inherently unknown or unrecognized. This distinction makes the word useful in precise descriptions of labelling and classification systems. It appears naturally in both British and American English and is broadly neutral in tone, ranging from practical everyday description to more technical discussion of records, data, and specimens.

Where does untagged come from?
Untagged is formed in English from un-, meaning “not,” tag, meaning “to mark or identify with a tag,” and the participial ending -ed. It is an ordinary English formation rather than a borrowing from Latin or Greek; the deeper historical origin of tag itself is uncertain. Related forms such as tagging, tagger, and taggable use the same root.
