Surface Forms
Morphology
The meaning is directly compositional: 'half' + 'shell' denotes literally one of two parts of a shell, and in culinary contexts refers to a shell split in half used for serving (e.g. oysters on the half shell). This is a literal, cross‑linguistically common construction, so a B1 learner who knows both words would be able to infer the MWE's meaning.
Etymology
The phrase half shell comes from the simple image of a shell cut in half and used like a small plate. That's why when you order oysters 'on the half shell', they arrive in the open shell halves as a serving dish.
