Not wanting to do something or feeling reluctant about it.

Disinclined → It is formed from "dis-" (meaning apart or not) and "inclined" (from Latin "inclinare", meaning to lean or bend). The word describes a state of not being inclined or willing to do something.
Think of being 'not willing' ('dis-') to 'lean' ('inclinare') towards something — that's why disinclined means not inclined to do it.
