Morphology

olein = oleic (opaque) = ole + in

Formed from the technical adjective 'oleic' with the chemical suffix '-in', but the combining form 'ole-' and the suffix are specialized chemistry morphemes unfamiliar to general learners.

Etymology

The word olein comes from the Latin root oleum meaning 'oil' and the ending -in that names substances, the same root you see in olive and oleic. So olein is literally the 'oil' part of fats and oils, which explains why it is the liquid portion found in many vegetable and animal fats.
