When you put two things side by side you begin to see the similarities and the differences between the two. When you look for what is similar, you’re comparing the two. When you look for what is different, you’re contrasting.
Compare and contrast may have different meanings, but the two words are very similar in practice. If you liken two things and make a note of everything similar between them, you likely will have noted the differences as well. Because of this the words are often used together as compare and contrast. If you use one or the other it’s because you want to emphasize the similarities or differences.
