Why can we not get diffraction from a wide slit illuminated by a monochromatic light ?

In diffraction experiment, when we choose two slits in place of a wide slit, the spectrum of the light obtained is very sharp and clear.
and we know, a clear and sharp spectrum can give us a precise measurements . so, This helps for precise measurements of wavelength of the monochromatic light .
That's why diffraction experiment is better than two slits set up or measuring the wavelength of monochromatic light .
