A lattice **L'** obtained from another lattice **L** by adding one or more sets of nodes is called a **superlattice of L**. The translation subgroup **T'** of **L'** is a supergroup of the translation subgroup **T** of **L**. The unit cell of **L'** is smaller than the unit cell of **L** and is therefore called a subcell.

In chemistry and material science literature the term superlattice is often incorrectly used to indicate a superstructure.
