Morphology

oligosaccharide = saccharide (semi-transparent) = oligo + saccharide + oligo

Formally built from the combining form 'oligo-' (few) + 'saccharide' (a sugar-related term), but both elements are technical combining forms that many B1 learners will not know.

Etymology

Oligosaccharide comes from the Greek parts oligo- meaning 'few' and saccharide meaning 'sugar'. So an oligosaccharide is literally 'a few sugars' linked together, which explains why the word describes a short chain of sugar units.
