-Ed and -Ing Adjectives: Bored or Boring? Interested or Interesting?
Grammar Rule in 30 Seconds
Use -ed for how you feel, and -ing for the thing that causes that feeling.
- Use -ed adjectives to describe a person's feelings: 'I am bored.'
- Use -ing adjectives to describe the cause of the feeling: 'The movie is boring.'
