There is a clutch slave cylinder that applies hydraulic pressure to depress the clutch. It is under the car by the clutch bell housing, on the driver's side. This is like a mini-master cylinder. Possibly it has a blown seal or all the fluid leaked out and you are not able to truly disengage the clutch even though the clutch pedal depresses by foot to the floor.
