Morphology

group + A

The phrase is a direct composition of 'group' (a category) and 'A' (the A blood type), so its meaning — the blood category marked by the A antigen — is immediately derivable from the constituents. This noun + label pattern is cross-linguistically common (e.g., 'grupo A', 'groupe A', 'A型') and would be clear to a B1 learner who knows both words.

Etymology

The noun group A comes from early blood tests where doctors named different blood types with letters. They called one type A because those red blood cells had an 'A' marker on them, so today group A means blood that carries that 'A' marker.
