Morphology

ethyl + ether

The noun is a straightforward modifier+head compound: 'ethyl' names the C2H5 group and 'ether' names the chemical class, so the combined meaning ('an ether containing ethyl groups' / the common solvent diethyl ether) is directly derivable from the parts. Although technical vocabulary, the semantic composition is regular and cross-linguistically transparent, so a learner who knows both constituents would predict the MWE's meaning.

Etymology

Ethyl ether mixes ethyl, a chemists' label for a small chemical part, and ether, an old word for a very light, airy substance. This image of a small chemical piece plus a light liquid helps explain why ethyl ether is a liquid that evaporates quickly and is flammable, and why it was once used 'to make people sleep' as an anesthetic and as a solvent.
