Worse or Worst: What’s the Difference and When to Use Each?

Many English learners—and even native speakers—mix up worse and worst because the two words look similar and both describe something negative. While they’re closely related, they are not interchangeable. Choosing the wrong one can make a sentence grammatically incorrect and change its meaning.
