Comparative adverbs are used to compare the intensity or manner of two actions or states. They are formed by adding "-er" to the end of the adverb, or by using "more" before the adverb. Here are examples of comparative adverbs and their rules:
-
Forming comparative adverbs with "-er":
- She runs faster than him.
-
Using "more" with longer adverbs:
- She sings more beautifully than her sister.
It's important to note that there are irregular comparative adverbs, where the comparative form doesn't follow the standard rules. For example:
- well becomes better
- badly becomes worse
- far becomes farther or further depending on the context (farther for physical distance, further for figurative distance or degree).
When using comparative adverbs, it's important to ensure that the comparison is clear and logical. They are often used in comparative sentences to show a difference in degree between two actions or states.
