The words can both be used interchangeably. However, the word "prone" usually describes a predisposition or a TEMPERMENT. Your upbringing might make you "prone" to be loud and talkative. The word " inclined" is used to describe a PREFERENCE or a decision made by a person. For example, you might be inclined to go to a movie if your friend said it was good. Hope this helps

Hey, how are you? I hope you are doing just fine! I shall provide you an explanation over the difference between these expressions: 1) ''Inclined to...'' = it means ''tending or disposed toward (something)'' E.g.: ''I'm inclined to give him the benefit of the doubt.'' E.g.: ''She is inclined to believe in you.'' E.g.: ''I should think that he is not inclined to work today.'' 2) ''prone to...'' = this expression is used to indicate that someone is likely to [do] something; apt to have something. When you say that you are prone to something, it means that you have a natural tendency toward something. E.g.: ''My boss is prone to anger when my work isn't done on schedule.'' E.g.: ''My sister is prone to sneezing because of her allergies.'' E.g.: ''He is prone to illness.'' ***NOTICE: Both ''prone to...'' and ''inclined to'' have pretty much the same meaning. Slight though it may be, the difference still exists. So, you should know that ''inclined to'' is more commonly said by native speakers rather than ''prone to'', and that ''inclined to'' conveys the idea of an action or decision made by the person , for example: ''I'm inclined to accept the truth'' or ''She is inclined to go home.'' Hope that helps!!!

I would say that if somebody is 'inclined' to do something, they have not yet fully made up their mind. If somebody is 'prone' to do something, it indicates weakness or predisposal to do something.

They have very similar meanings. In my mind, prone is more incidental and possibly more negative. Someone prone to doing something might not be aware they do it often ("He is prone to running late") or it might be something they don't have control over it ("I'm prone to getting acne"). Inclined is more intentional. Usually when used with people it actual means they want to do whatever it is they are inclined to ("I am inclined to go to the party"), but it has a pretty formal sound to it. The words are more similar when talking about objects instead of people, and basically 'to be likely to' or to 'to tend to', but I would still say prone has a negative sound ("glass is prone to breaking"), and inclined has a formal sound ("That is inclined to happen"). I hope this was helpful!
