Monomer (noun)

1. A simple molecule that can bind chemically with other similar molecules to form a polymer.
2. A subunit of a polymer or a macromolecule that can be chemically linked with similar units to form a polymer chain.

Origin:

Late 19th century; from greek μόνος (mónos) meaning 'single' and μέρος (méros) meaning 'part'.

Examples:

1. The monomers of the polymer were linked together through a chemical process.
2. The scientists studied the reaction of different monomers with each other.
3. The monomer building blocks were polymerized to form a long chain polymer.
4. The monomer units are covalently bonded to form the final polymer.
5. The monomer molecules are combined to form a polymer in a chemical reaction.
