Morphology

polysaccharide = saccharide (transparent) = poly + sacchar + ide

The meaning is a straightforward combination of 'poly-' meaning many and 'saccharide' meaning a sugar-related compound.

Etymology

The word polysaccharide comes from poly- 'many' and saccharide which is related to 'sugar', so it means 'many sugars'. That's why common substances like starch, cellulose, and glycogen are called polysaccharides: they are long chains of sugar units used for energy or for plant structure.
