Morphology

diethyl + ether

The compound is compositional: 'diethyl' specifies two ethyl groups and 'ether' names the chemical class/solvent, so together they denote an ether molecule bearing two ethyl substituents. Although this is technical chemical terminology, the meaning is directly derivable from the constituent parts, so a learner who knows both constituents can infer the MWE's meaning.

Etymology

Diethyl ether is a name that shows its parts: di- means two, ethyl is a small part of the chemical, and ether was the name for light, sweet-smelling liquids. That's why the name refers to a clear, very flammable liquid once used 'to make people sleep' in surgery and to 'dissolve other things'.
