Sense: adjective/1
Tagged, labeled, marked, identified, and tracked all refer to attaching information to an object, but they differ in method and purpose. Tagged suggests a physical attachment such as a paper tag or an electronic device, and often implies the object can be located or monitored — for example, tagged luggage is easier to find. Labeled focuses on written information fixed to an item, like a price or ingredient list; it does not suggest electronic tracking. Marked is the broadest term — a marked package could have a pen stroke, a stamp, or a sticker, without implying a specific system. Identified emphasizes that the object's ownership or nature is known, rather than the attachment method. Tracked specifically means the location or status is monitored over time. Compare: 'the tagged birds provided migration data' (tracking implied), versus 'the labeled jars listed ingredients' (no tracking), versus 'the marked trees showed the hiking trail' (simple visible indication).

Etymology
The adjective 'tagged' comes from the verb 'tag', which in turn traces back to the Middle English noun 'tagge' — a small piece of metal at the end of a cord or lace. By the 1600s, 'tag' referred generally to any small label or marker attached to something. The computing sense of 'tag' (assigning a keyword to data) emerged in the late 20th century as file systems and databases needed flexible labels for organizing digital information. The adjective form 'tagged' has been used since the 1800s for physical markers and since the 1990s for digital labels.
