Fist off, you did a really great job on this post. I can clearly see that you put a lot of work into it. I also like the topic you chose. I think it's important to realize that sometimes words can have double meanings. This can be confusing to people when your using the same words in different instances but they have different meanings. It's just like you explained in your examples. I think this does help non native speakers of the language a lot and I'm sure that they would appreciate the effort you put into this.
