Morphology
mast + cell
Although 'cell' is transparent, the component 'mast' does not convey the biomedical sense (it is a historical/technical label, not the common meaning like a ship's mast), so the combined term refers to a specialized histamine-containing cell rather than a compositional 'mast' + 'cell' meaning. The MWE is a technical, etymologically motivated term whose overall meaning cannot be derived by a B1 learner who only knows the ordinary word meanings.
Etymology
The term mast cell may come from an old German word mast meaning 'to fatten' or 'to feed'. Early scientists saw these cells full of tiny packets and used the image of a cell stuffed with stores, so that's why mast cells are remembered as cells that hold and release chemicals in allergic reactions.
