I agree with the above posting. Flaperons are ailerons used as flaps to increase the wing incidense. Spoilerons are ailerons used as spoilers to decrease the wing incidense. When used in conjunction with elevators, they are just coupled, or slaved flaperons or coupled, or slaved spoilerons. They are coupled flaperons, when they go in opposite direction of elevator (elevator causes an increase in angle of attack and flaperons causes an increase in wing incidense, or vice versa). They are coupled spoilerons when the opposite takes place.
The reason for calling an uncoupled flaperon just that, flaperon, and not just flaps, is that it uses the flaps for this function (full wing length or not) but do not lose the aileron function.
If it is on a tail less delta plane, it is called elevons, and the mix would be on all the time to control roll and pitch.
