KK: /dɪsɪnˈklɪneɪʃən/
A feeling of not wanting to do something or a reluctance to engage in an activity.

Disinclination → It is formed from "dis-" (meaning apart or away) and "inclination" (from Latin "inclinare", meaning to lean or bend). The word describes a state of being away from a tendency or preference, indicating a lack of willingness or desire.
Think of being 'away from' ('dis-') a 'leaning' or 'tendency' ('inclination') — that's why disinclination means a lack of desire or willingness.
