Morphology

killer + T + cell

The phrase is compositionally built: 'killer' (one that kills) + 'cell' (biological unit) yields the straightforward idea of a cell that kills, and the 'T' functions as a subtype marker (a specific kind of cell). Although 'T' is a technical label, it does not block the basic inference that this is a cell whose role is to kill infected or abnormal cells, so a learner knowing the constituents would readily grasp the core meaning.

Etymology

Killer T cell gives a simple picture: killer suggests something that destroys, and T cell is a blood cell that fights sickness. So the name reminds us these cells find and 'kill' cells that have a virus or are cancerous in the body.
