If anyone has ever told you to do something you didn’t want to do, you’ve felt a disinclination, a doubt about participating. Having a disinclination means you’re just not into it, so you hesitate.
In Herman Melville’s short novel “Bartleby, the Scrivener,” when anyone asks Bartleby for a favor, he always replies, “I would prefer not to.” That’s an example of a disinclination — the feeling that there are other things you’d rather be doing. If someone tells you to eat a lightbulb, you might feel a disinclination to do that, and for good reason. The Latin roots of the word roughly translate to “unable to bend,” which describes your unwilling disinclination quite well.
