Morphology
organophosphorus = phosphorus (opaque) = organo + phosphorus
Although the word is built from a technical combining form plus 'phosphorus', the meaning is not recoverable for an average learner from the parts alone.
Etymology
Organophosphorus is made from organo- and phosphorus, with organo- like organic meaning 'carbon-based' and phosphorus the element 'phosphorus'. So an organophosphorus is a chemical compound that contains both carbon and phosphorus, which explains why some are used as pesticides and why they can be harmful.
