Morphology

chlorine = chlor + ine

Formed from the combining element 'chlor-' and the chemical suffix '-ine', neither of which is a standalone English base a B1 learner would use to infer 'a yellow-green toxic gas'.

Etymology

Chlorine comes from the Greek word chloros, which means 'green'. It shares the same root as chlorophyll, the green color in plants, and that is why chlorine was named for the yellow-green color of the gas used for disinfecting and bleaching.
