Morphology

actinomycosis = Actinomyces (opaque) = actin + myc + osis

The disease name is formed from a scientific genus name plus the medical suffix '-osis', a formation that is specialist and not readily interpretable by an average B1 learner.

Etymology

Actinomycosis comes from Greek parts actino- 'ray', myco- 'fungus', and -osis 'disease', because the germs that cause it make thread-like, ray-shaped clumps that looked like a little sun or fungus to early doctors. So actinomycosis literally means a 'ray-fungus disease', which helps explain the name for a long, painful infection with swelling and pus, even though it is actually caused by bacteria rather than a true fungus.
