Morphology

organophosphate = phosphate (semi-transparent) = organo + phosphate

The combining form 'organo-' signals an organic (carbon-containing) derivative of 'phosphate'; the technical chemistry sense makes it only partly transparent for a general B1 learner.

Etymology

Organophosphate combines organo-, from the word 'organic' meaning 'made from carbon or living things', and phosphate, the chemical group from the element phosphorus. So an organophosphate is a carbon-based chemical with a phosphate group, and many of these have been used as insect killers because they affect the nervous system.
