The Compare & Contrast Essay
To compare is to examine how two or more things are similar; to contrast is to see how they differ. A compare-and-contrast essay does one or both — sometimes a prompt asks for only similarities or only differences ("Examine how the economies of Spain and China are similar" is compare-only).
Choosing and planning: pick related subjects (two people in the same profession, two products in the same category) so there is enough common ground. List all similarities and differences first — a Venn diagram helps — then form the thesis.
Three ways to structure the body:
| Structure | How it works | Best for |
|---|---|---|
| Block (subject by subject) | all about subject 1, then all about subject 2 | giving each subject full attention |
| Point-by-point (alternating) | one point for subject 1, then the same point for subject 2 | emphasising the connection |
| Similarities & differences | one paragraph of similarities, one of differences | building to a key point |
Keep the criteria parallel. When you contrast, compare the same features for each subject. Weak: "Aaron is tall and strong; Bruce is handsome and intelligent." (different criteria). Strong: "Aaron is tall, while Bruce is short. Aaron is strong; in contrast, Bruce is weak." (same criteria — height, strength).
The writing process is the usual one: brainstorm → choose a structure → draft → revise → proofread.
Model essay (point-by-point) — communication then and now:
While present and previous means of communication are similar in form, they differ in speed and range. One similarity relates to form: in the past both written (letters) and oral (telephone) forms were used; similarly, people today use written forms (email, texting) and oral forms (phone, voice messages). However, there are clear differences, the most notable being speed: a letter took days, whereas an email arrives almost instantly. Another difference is range: fifty years ago the main tools were the telephone and letter, by comparison today there is a vast array — video calls, apps, and social media. In conclusion, methods have greatly advanced; some similarities remain, but the differences in speed and range are significant.
Signal words: comparison — similarly, likewise, both … and, just like, similar to, the same as; contrast — however, in contrast, on the other hand, while, whereas, differs from, unlike.
Tip: The block method is easier to write; the point-by-point method is usually clearer because it makes the similarities and differences explicit side by side.
Common mistake: Contrasting on mismatched criteria (height vs. looks). Always compare the same feature for both subjects, using parallel contrast words (while, in contrast, on the other hand).
