1. Comparative adverbs are used to ‘compare’ two objects or people. They often begin with "more" or "less." 

              For example: "She is more beautiful than I am."

2. Comparative adverbs are also used to compare parts of a whole, such as "They are better players than we are." The part of the whole being compared must be less than the other comparison part(s).

3. Comparative adverbs do not always mean that one thing is better than another thing.

For example: "He is taller than most boys his age," does not mean that he is taller than all boys his age; it means that he is taller than most boys his age.

‍

Comparative adverbs are used to compare two or more things. They show when one thing is greater, less, or equal to another. They can be used in both comparisons and adjectives. Adverbs of degree are used to show how much something is, such as "very" or "extremely."

A comparative adjective describes a noun by comparing it to another noun or pronoun.

‍

A pronoun can be used with a comparative adjective to create an inclusive comparison.

Examples: 

"The book is very long" - this is an ambiguous sentence because it could mean either the book contains many pages or that the pages are longer than other books. This sentence would make sense if we replaced 'long' with 'longer' and 'many' with 'more.'

More examples:

• “John runs faster than Tim.

• “John works more carefully than Tim.
