Also, "finish" is a much more common word. The word "finalize" is something that you would rarely if ever need to use in casual spoken English.

Thanks a lot.

"To finish" and "to finalize" something have very similar meanings as they both mean "to end something", but "to finalize" something usually means that there is still more to be done e.g. I have finalized my application, but now I need to send it. This means you have finished a part of a process, but you now need to do something else. "To finish" means to completely end something e.g. I've finished my meal. This means you've done something and there's nothing left to complete. I hope that makes sense^^

You "finish" a physical action -- I finished my meal. I finished that project. "Finalize" means to finish planning. I finalized the plans for the project. But when the project is completed, you finished the project. You would not "finalize" eating your meal. You can say you finished planning something, that is also correct. In general. Think of finish as a physical action and finalize for planning.
