Morphology
chlorpyrifos = chloro + pyr + ifos
This is a technical chemical name formed from specialized combining forms (e.g. chloro-, pyr-, -phos/-ifos) that are not productive or familiar to average learners, so the meaning cannot be derived from common English vocabulary.
Etymology
The word chlorpyrifos comes from parts that describe its chemistry: chloro- means 'chlorine', pyr- comes from a chemical called 'pyridine', and -phos is like phosphate, meaning 'phosphorus'. So, the name shows it contains phosphorus and chlorine, which explains why chlorpyrifos is a chemical made to kill insects.
