Morphology
ABO + system
While 'system' is a transparent, general noun, 'ABO' is a specialized acronym referring to blood-group antigens and is not a regular lexical item whose meaning a B1 learner can derive from its parts. Without prior domain knowledge of what 'ABO' denotes, the overall meaning 'a blood-group classification' cannot be inferred, so the expression is opaque to typical learners.
Etymology
ABO system gives a simple picture: imagine red blood cells wearing tiny 'name tags' marked A or B. If a cell has no tag it is O, and if it has both tags it is AB, so doctors use these tags to sort blood into the four groups A, B, AB, and O.
