Morphology

Actinomyces = actin + myces

A specialized taxonomic name built from Greek combining forms ('actin-' + 'myces') that are not productive or meaningful to an average B1 learner, so the meaning cannot be derived from the parts.

Etymology

The word Actinomyces comes from Greek parts actino- meaning 'ray' and -myces meaning 'fungus'. It was named because these bacteria grow in long, ray-like threads that look a little like a mushroom, so the name helps you remember they are thread-growing, fungus-like bacteria that can cause infections.
