Morphology

trichloromethane = methane (semi-transparent) = tri + chloro + methane

The name is a systematic chemical formation (tri- 'three' + chloro- 'chlorine' + methane) and is clear to those familiar with chemical combining forms but not to general B1 learners.

Etymology

Trichloromethane breaks into three parts: tri- 'three', chloro- 'chlorine' as in chlorine, and methane 'a simple gas', so the name means a methane molecule with three chlorine atoms. That's why trichloromethane is the chemical also called chloroform, which was once used as an anesthetic but is now known to be toxic.
