Morphology
actinomycin = actinomyces (opaque) = actinomyces + in
Formed from the bacterial name Actinomyces plus the chemical substance suffix '-in' (or antibiotic-forming suffix '-mycin'); this is a technical nomenclature not semantically transparent to general learners.
Etymology
The word actinomycin comes from the parts actino- and -mycin, where actino- means 'ray' and -mycin comes from a word for 'fungus'. This name describes the soil bacteria that make the red antibiotic — they grow as ray-like threads like a fungus, and the -mycin ending is used for many antibiotics, so actinomycin is an antibiotic made by those 'ray' bacteria.
