Morphology
Phytophthora = phyto + phthora
The name is a scientific coinage from Greek combining forms ('phyto-' = plant, '-phthora' = destruction) that are not standalone English words, so an average B1 learner cannot derive the meaning from familiar English components.
Etymology
Phytophthora comes from Greek parts phyto- meaning 'plant' and -phthora meaning 'destruction'. So, Phytophthora is literally a 'plant destroyer', which explains why these organisms cause serious diseases in crops and garden plants.
