In single slit diffraction pattern, the point where secondary waves reinforce each other, resulting in the maximum intensity at that point, is called central maximum.
Most of the light is concentrated in the broad CENTRAL DIFFRACTION MAXIMUM. There are minor seconday bands on either side of the central maximum, known as secondary minima.
