Comparative form:

Superlative form:

The comparative form of an adjective in English is usually created by adding the suffix "-er" to the end of the word, or by preceding the adjective with the word "more": 

• One-syllable adjectives 
  Add "-er" to the end of the word: 
  
• Old: Becomes "older" 
  
• Clean: Becomes "cleaner" 
  
• Slow: Becomes "slower" 
  
• 
  
  
  
• Adjectives ending in "-e" 
  Add "-r" to the end of the word: 
  
• Safe: Becomes "safer" 
  
• Nice: Becomes "nicer" 
  
• 
  
  
  
• Adjectives ending in a vowel and a consonant 
  Double the last letter before adding "-er": 
  
• Big: Becomes "bigger" 
  
• Hot: Becomes "hotter" 
  
• 
  
  
  
• Adjectives with two or more syllables 
  Precede the adjective with "more": 
  
• Careful: Becomes "more careful" 
  
• Interesting: Becomes "more interesting" 
  
• 
  
  
  

There are also irregular comparative forms, where the entire word changes, rather than just adding a suffix or word in front. 

Comparative adjectives are used to compare two things or show change. For example, "This hotel is cheaper than the one on the beach". 

Superlative form:

Superlative adjectives

Superlative adjectives are used to describe an object which is at the upper or lower limit of a quality (the tallest, the smallest, the fastest, the highest). They are used in sentences where a subject is compared to a group of objects.

Noun (subject) + verb + the + superlative adjective + noun (object).

The group that is being compared with can be omitted if it is clear from the context (final example below).

Examples

• My house is the largest one in our neighborhood.
• This is the smallest box I've ever seen.
• Your dog ran the fastest of any dog in the race.
• We all threw our rocks at the same time. My rock flew the highest. ("of all the rocks" is understood)
