Morphology

dichlorodiphenyltrichloroethane = phenyl + ethane (opaque) = dichloro + diphenyl + trichloro + ethane

The term is a technical chemical name composed of combining forms (dichloro-, diphenyl-, trichloro-, -ethane) whose meanings are specific to chemistry and not recoverable by average B1 learners from the components.

Etymology

Dichlorodiphenyltrichloroethane is a very long chemical name made of smaller parts: di- 'two', chloro 'chlorine', diphenyl 'two ring groups', tri- 'three', chloro 'chlorine', and ethane 'a two carbon chain'. So, the name simply describes the parts of the molecule and is the formal chemical name for the insecticide commonly called DDT.
