The difference between "controversial" and "contested"
Hello everyone.
I have a question regarding the difference between "controversial" and "contested".
Recently I started reading news in English, and I find these words pretty often when I am in politics sections.
(controversial topics, contested islands, etc)
I have a rough idea for the meaning of both, but I was wondering if there is any difference in how to use.
Are they interchangeable?
It would be really appreciated if anyone help me with this.
Thank you for your help in advance:)
