Morphology
penicillin + F
The phrase combines 'penicillin' (an antibiotic) with the letter 'F' as a label, which transparently signals a particular subtype or variant of the drug. Letter-based naming of variants is a common, compositional convention across languages, so a B1 learner who knows both constituents would infer it denotes a specific form of penicillin (even if they would not know detailed historical facts).
Etymology
Penicillin F gets its name from penicillin, the medicine first found in the mold Penicillium, and scientists added the letter 'F' when they identified this particular type. So penicillin F means 'a naturally occurring form of penicillin' that was found in the mold and used as an antibiotic.
