Morphology
polyacrylamide = acrylamide (semi-transparent) = poly + acryl + amide
The word is a regular prefixation of the technical base 'acrylamide' with 'poly-', but the specialized chemical base limits immediate accessibility for general learners.
Etymology
The word polyacrylamide breaks into poly- meaning 'many' and acrylamide, which is related to acrylic, a common plastic used in paint and nails. So polyacrylamide is a material made of many small 'acrylic' parts joined together, which is why it forms gels and absorbs water.
