Compare and Contrast Structure

Writers often help us understand something by holding it up against something else. Seeing how two things are alike and different is a structure you will meet often.

Compare and contrast is a text structure that shows how two or more things are similar and different. Comparing points out similarities; contrasting points out differences. Signal words include “like,” “both,” and “similarly” for similarities, and “unlike,” “however,” and “on the other hand” for differences. This structure helps readers weigh options and see relationships.

How the Structure Works

A compare-and-contrast passage moves back and forth between two subjects. It might discuss city life and country life, two authors, or an old method and a new one. The signals guide you: “both cities have museums” marks a similarity, while “unlike the city, the country has little traffic” marks a difference. Writers organize this two ways. Some describe everything about one subject, then everything about the other. Others go point by point — comparing cost, then comparing convenience, then comparing safety. Knowing which arrangement you are reading helps you keep the two subjects straight. As you read, it can help to picture two columns in your mind, sorting each detail under the subject it describes.

Answering Comparison Questions

Questions may ask how two things are alike, how they differ, or what conclusion the comparison supports. The trick is to attach each detail to the right subject. If a passage says one plan is cheaper but slower and another is faster but costly, do not mix up which is which. Watch the contrast signals carefully — “however” and “on the other hand” tell you a difference is coming, and “similarly” tells you a likeness is coming. Some wrong answers describe a true fact but pin it on the wrong subject. Keeping your mental columns clear, and rereading the signal words, ensures you match each trait to the thing it actually belongs to.
