Special VFR is a sub category of Visual Flight Rules (VFR) flight. Permission to operate under Special VFR within a Control Zone, in meteorological conditions not meeting Visual Meteorological Conditions (VMC) minima, is given to a flight by means of an Air Traffic Control clearance. Such traffic is effectively also Controlled VFR.
Both terms are defined in ICAO Doc 9713.
