Spelling Rules for Comparative & Superlative Adjectives

At ESL Library, we think spelling is swell! We’ve recently completed a blog post, grammar resource, and grammar lesson on spelling rules for adding ed to regular past verbs.

The rules for adding er to form comparative adjectives and est for superlative adjectives are quite similar to the rules for adding ed to regular past verbs. If your students aren’t familiar with form and function of these adjectives, review our posts on comparative adjectives and superlative adjectives before presenting the spelling rules below. You can also check out the related materials at the end of this post for further examples and practice.
