jacket
[C] Countable
pl: jackets
This term carries a strong association with utility and layering. It suggests a garment that is more substantial than a shirt but less heavy than a full overcoat, often implying a functional transition between indoor and outdoor environments. In a technical or publishing sense, the word evokes the image of a removable shell. This shift from clothing to packaging maintains the core concept of a protective outer layer that shields a more fragile interior.
Used for individual pieces of clothing or book covers.
