Juxtaposition

"Juxtaposition is the placement of two things (usually abstract concepts, though it can refer to physical objects) near each other."

As defined by Wikipedia

Juxtaposition also means a method of placing close together or side by side, especially for comparison or contrast. It is use for comparing or contrasting between two things usually. This method is popular use in a lot of presentation because it is a creative process made to channel idea or meaning to people. In class, our lecturer, Mr. Mustafa tries to explain to us about what is the meaning of juxtaposition by asking us a question. The question is about the wall in the lecture room. He asked, what the difference you can see between the wall? Why is it one of the wall orange color and the other one is yellow color? What is the wall try to communicate with us? So, many students come with their own opinion, and the lecturer tries to conclude it. In order to understand it easily, the lecturer tells us that juxtaposition is just about communicating idea with us.

Thank you. :D
