The meaning of juxtaposition:
- An act or instance of place close together or side by side, especially for comparison or contrast.
- The state of being close together or side by side.
We know that the word Juxtapose means to place two things side by side to compare and contrast them. A sentence would be something like: "Juxtaposing the two essays revealed the huge differences in the author's viewpoints."
In literally, it means placement together, but it isn't really used that literally. You wouldn't say that the chair is juxtaposed next to the table.
