# Twin lattice

A twin operation overlaps both the direct and reciprocal lattices of the individuals that form a twin; consequently, the nodes of the individual lattices are overlapped (restored) to some extent (twinning (effects of). The lattice that is formed by the (quasi)restored nodes is the *twin lattice*. It corresponds to the crystal lattice in twinning by merohedry and to a sublattice of the crystal (individual) in twinning by reticular merohedry.
