Memory Aids
Mnemonic
Think: METHYL (a common chemical group) + METHACRYLATE (sounds like 'acrylate', a type of plastic). It's the methyl version of methacrylate, used to make clear plastics like Perspex.
Conceptual Metaphor
BUILDING BLOCK / RAW MATERIAL (It is the 'monomer' or fundamental unit that is linked together to build the larger 'polymer' structure, like bricks in a wall).
