How do we form the comparative degree of adjectives?

To form the comparative degree of adjectives, we typically add the suffix "-er" to the end of the adjective. However, there are some rules and exceptions to consider.

1. For most one-syllable adjectives, we add "-er" to the end of the adjective. For example:
- tall → taller
- fast → faster
- big → bigger

2. For one-syllable adjectives ending in a consonant-vowel-consonant pattern, we double the final consonant before adding "-er". For example:
- hot → hotter
- big → bigger
- thin → thinner

3. For adjectives with two or more syllables, we use the word "more" before the adjective. For example:
- beautiful → more beautiful
- intelligent → more intelligent
- expensive → more expensive

4. Some adjectives have irregular comparative forms that do not follow the usual rules. Here are some common examples:
- good → better
- bad → worse
- far → farther/further
- little → less

5. When comparing two things or people, we use the word "than" after the comparative form. For example:
- She is taller than her sister.
- This book is more interesting than the previous one.

It is important to note that there are exceptions and irregularities in forming the comparative degree of adjectives. Therefore, it is essential to consult a dictionary or grammar guide for specific adjectives that do not follow the general rules mentioned above.
