Suffix: -er and -est

When you add -er to an adjective you create what is called the comparative form of that adjective. Here are some examples: 


	Adjective		Comparative
	  tall			  taller
	  small			  smaller
	  pretty		  prettier
	  scary			  scarier
	  big			  bigger
	  large			  larger
As you can see, when adding -er to an adjective you sometimes must drop the y and add -ier and sometimes you must double the final consonant.

Here are some adjectives in their comparative form used in sentences: 


  Jill is smaller than Jack, but she is smarter than him.

  The trees by the creek are taller than those on the hill.

  Lisa's mice are fatter than John's mice.
