Slave cylinder. Even you can change that yourself.

I've noticed recently that my clutch isn't always disengaging fully (on my 92 NA). I usually have to pump it a few times before it gets consistent... after driving a bit it's fine.
Today was the worst. I haven't driven the car in about a month so I went out and started it... I had it in first, pushed in the clutch, and to my surprise the car inched forward like it was still in gear.
I decided that maaaybe it's time to fix this... what would be the problem here? Fluid is full... slave? Master?
Looks like it's time for a trip to Rogue

Read the link. It would cause disengage problems. If you pull the right-front tire, it is a piece of cake to change. You may even get by by rebuilding it. (Even easier....a spring, a plunger and a rubber boot)

You can one at any parts store, about $45.
