Morphology
penicillin + G
The phrase combines a known noun 'penicillin' with the letter label 'G', so a B1 learner would likely infer this refers to a specific type or variant of penicillin rather than a completely new concept. However, the precise clinical meaning and properties (e.g., that it is the naturally occurring benzylpenicillin and its spectrum/economic role) are specialized and not predictable from the constituents alone, so partial but not full transparency applies.
Etymology
Penicillin G gets its name from the mold 'Penicillium', because the first penicillin came from that mold, and scientists add the letter G to tell different kinds apart. So penicillin G means the original natural form of penicillin that is used as a main ingredient in many antibiotics.
