Review means to look at something again carefully, examining it to understand it better or to form an opinion about it. When you review your notes before a test, you're going through the material again to refresh your memory and catch anything you might have missed the first time. When a teacher reviews your essay, she's reading it closely to evaluate your work and offer suggestions.

The word also refers to the evaluation itself. A book review is someone's written opinion about whether a book is worth reading. Movie reviews help people decide which films to watch. Restaurant reviews describe the food, service, and atmosphere so others can judge whether to eat there.

Scientists peer review each other's research, checking calculations and questioning conclusions before new discoveries get published. This process helps catch errors and makes science more reliable. Judges review court decisions to see if earlier rulings were fair and legally sound.

Notice how reviewing is different from just rereading or glancing over something. When you truly review, you're engaging your critical thinking: questioning, evaluating, and looking for strengths and weaknesses. You might review the season highlights to see what your team did well and what needs improvement. The word suggests both looking backward at something already done and thinking forward about what it means or what comes next.
