You’ve probably already learned that we can use -ED adjectives to describe how a person feels, and -ING adjectives to describe the thing, person, situation, or event that causes the feeling:
I’m tired. My
job is very tiring.
“tired” describes “I”, and “tiring” describes “job”
“tired” describes “I”, and “tiring” describes “job”
We’re bored. This
movie is boring.
