Qual é a diferença entre contrary e converse e adverse ?Podes indicar apenas respostas exemplo.

Contrary:
To be opposed to something usually saying or arguing for the exact opposite. You can almost always put "despite" instead of "contrary" and the sentence will still make sense and have almost the same meaning.
Example 1:
Josh: "This car is really hot!"
Bill: "On the contrary! this car is quite cold!"
Example 2:
Prime minister: "Contrary to public opinion, i think the new project to build roads will go well!"
Prime minister: "Despite public opinion, i think the new project to build roads will go well!"
^^^both of these sentences mean almost the exact same thing^^^

Here is another sentence that explains the meaning fully:
Prime minister: "Contrary to public opinion, i think the new project to build roads will go well!"
What he is saying is: "The opinion of the public is that the new road building project will do badly, but i think the opposite! i think it will do well!"
--------------------------
Converse:
Converse has two meanings.
One is to have a conversation
"the two men were conversing"
This means the two mean were talking.

The other meaning is something having traits that are the opposite of something else already talked about. Converse is often used to compare two things by using "conversely".
General: "My tank is big"
lieutenant: "Conversely, my tank is small"
--------------------------
Adverse:
Adverse also has two meanings.
Adverse can mean dislikes, and/or avoids usually.
But it can also mean harmful or unfavourable.

Example:
"That man is quite adverse to running!"
This means the man doesn't like running, and avoids running whenever he can.

Example 2:
"She had an adverse reaction the the medicine"
She took the medicine and had an allergic reaction or the medicine had an unwanted effect on her.
--------------------------
This isn't the best explanation but these words are quite difficult to explain. I think these words are the type of words you need to get a feeling for after hearing them used quite a bit.

All the same i hope this helps. Good luck!
