Morphology

pathogen = patho + gen

The elements are Greek combining forms ('patho-' meaning disease, '-gen' meaning producer) that are not standalone English words, so learners cannot reliably derive the meaning from familiar English bases.

Etymology

Pathogen comes from Greek parts patho- 'suffering, disease' and -gen 'to produce'. So a pathogen is literally a 'producer of disease', which is why we use the word for viruses and bacteria that cause illness.
