Morphology

group + AB

The meaning is directly compositional: 'group' (a set or classification) combined with 'AB' (the blood type expressing both A and B antigens) yields the blood group AB. This follows straightforward naming conventions for blood types and is cross-linguistically and domain-wise predictable, so a learner who knows both constituents would understand it.

Etymology

Group AB names a 'blood group' whose red blood cells carry both letters A and B. Because the cells really show 'both A and B', doctors call this type group AB, which explains its special rules for giving and receiving blood.
