A disinclination is a lack of willingness to do something — you could do it, but you would rather not. It almost always comes with “to”: a disinclination to speak, a disinclination to travel. Though actually, it is a stiff, rather old-fashioned noun. In everyday talk most people would say “I don’t really want to” or “I’m not keen.” You use this word when you want to sound polite and a little distant, as if you are describing a feeling rather than slamming the door. It is weaker than hate or fear. You are not attacking the thing; you just have no pull toward it.
