A very large molecule made by joining many smaller molecules together.
A polymer is a substance made from very large molecules. Each large molecule is built by joining many smaller molecules called monomers. The prefix poly- means “many”, so a polymer contains many monomer units joined together.

A substance made of very large, long-chain molecules in which repeating units are joined by covalent bonds.
A polymer is made of very large molecules. Each molecule has a long chain containing a pattern of atoms that repeats many times. Small molecules called monomers can join together to produce these chains; the recurring section of the finished chain is its repeating unit.

A substance whose molecules are very long chains made by joining many monomers, giving it a high average relative molecular mass.
During polymerisation, very many monomers become connected by covalent bonds, producing a long-chain molecule called a polymer. Because a polymer molecule contains so many atoms, it has a high average relative molecular mass.

Exam tips

1
Do not say that polymers melt by breaking covalent bonds. On melting, the polymer molecules separate as intermolecular forces are overcome; the covalent bonds within each chain remain intact.
2
When identifying a polymer diagram, look for a repeating section of a long covalently bonded chain. It may be shown inside brackets with bonds crossing the brackets and an $n$ outside.
3
Do not describe a polymer as a giant covalent structure. A polymer sample contains separate, very large molecules, so intermolecular forces act between its chains.
