Morphology
severe + combined + immunodeficiency
The meaning is directly compositional: 'severe' (very serious) + 'combined' (affecting multiple components) + 'immunodeficiency' (weakened immune system) yields a very serious form of immune weakness affecting more than one arm of immunity. While clinical specifics (inheritance, T‑cell absence) are specialized, the general sense is predictable from the constituents and would be understood by a learner who knows those words.
Etymology
Severe combined immunodeficiency is made of severe, meaning very bad, combined, meaning more than one part, and immunodeficiency, meaning 'a weak immune system'. It describes a rare inherited condition where the body's immune 'army' is missing many soldiers, so the person is very vulnerable to infections.
