Most adjectives have comparative and superlative forms. When you compare two things, use the comparative form. For example, Sarah is taller than Amy. When you compare a group of things, use the superlative form to show the most or the best in that group. Remember to put "the" in front of the superlative adjective. For example, Sarah is the tallest in her class. Usually, you add -er to a short adjective for its comparative form and -est for its superlative form. But there are exceptions, like funny, funnier, funniest, or little, less, least. Ready to test your knowledge? Grab your pencil and fill in the blanks!
