Morphology

CD8 + cell

The compound is compositionally transparent: 'CD8' names a membrane protein involved in immunity and 'cell' is a living unit, so a learner who knows both constituents can infer it is a cell that carries the CD8 protein. While the full immunological function (cytotoxic T cell activity) is specialist knowledge, the basic referent is directly derivable from the parts.

Etymology

CD8 cell gets its name from a small protein on the cell surface called CD8, which acts like a visible 'badge' to help the immune system recognise the cell. The word cell means a tiny living part of the body, and these 'badged' cells act like soldiers that find and kill virus-infected or abnormal cells, so the name points to their job.
