Adjectives: -ed vs. -ing (Feeling vs. Cause)
Grammar Rule in 30 Seconds
Use -ed for how you feel and -ing for the thing or person that makes you feel that way.
- Use -ed to describe an internal emotion or state, like 'I am bored' (max 20 words).
- Use -ing to describe the characteristic of a thing, like 'The movie is boring'.
- People can be both: 'He is bored' (feeling) vs 'He is boring' (personality).
Overview
Words ending in -ed and -ing are different. -ed is for feelings. -ing is for things that make feelings.
This is very important. 'I am bored' and 'I am boring' are different.
-ed says how you feel. -ing says what you are like.
How This Grammar Works
- The present participle (
-ing) carries an active, causative meaning. The noun it modifies is the agent or source that actively produces an emotion. It performs the action of the verb on something or someone else. It answers the question, "What is the quality of the person/thing causing this feeling?" - Think of it as an active sentence: The story amuses the children. The story is the agent. Therefore, it is an
amusingstory. - The long meeting tires the employees. The meeting is the cause. Therefore, it is a
tiringmeeting.
- The past participle (
-ed) carries a passive, receptive meaning. The noun it modifies (almost always a person or animal) is the recipient or experiencer of the emotion. The action of the verb has been done to them. It answers the question, "How does this person/animal feel?" - Think of it in the passive voice: The children are amused by the story. The children are the recipients. Therefore, they are
amused. - The employees are tired by the long meeting. The employees are the experiencers. Therefore, they are
tired.

Smart Tips
Default to -ed. It is much more common to talk about your feelings than to describe yourself as a 'source' of something.
Always use -ing. These things don't have brains, so they can't have -ed feelings.
Replace 'good' or 'bad' with specific participial adjectives like 'captivating', 'harrowing', or 'stunning'.
Remember the preposition 'in'. It's almost always 'interested in [something]'.
Pronunciation
-ed endings
The -ed can be pronounced as /t/, /d/, or /ɪd/. For example, 'relaxed' ends in /t/, 'tired' in /d/, and 'excited' in /ɪd/.
-ing nasal
The 'g' in -ing is usually not a hard 'g'. It's a soft nasal sound /ŋ/.
Emphasis on the adjective
That was SO boring! (Arrow up on SO)
Conveys strong emotion or exaggeration.
Memorize It
Mnemonic
ED is for the End-user of the feeling. ING is for the Initiator of the feeling.
Visual Association
Imagine a battery. The -ING is the charger (the thing giving the energy/feeling), and the -ED is the phone (the thing receiving the energy/feeling).
Rhyme
If it's how you feel, -ED is the deal. If it's what you see, -ING it must be!
Story
Ed was a very tired man. He had a very tiring job at the 'Ing' factory. Every day, the 'Ing' machines made an annoying sound, which made Ed feel very annoyed. By the end of the day, Ed was exhausted because the work was exhausting.
Word Web
Challenge
Look around the room. Find one thing that is 'interesting' and explain why you are 'interested' in it out loud.
Cultural Notes
Brits often use 'knackered' (slang for exhausted) or 'gutted' (slang for very disappointed).
Americans frequently use 'bummed' or 'bummed out' for disappointed.
In international business, using 'challenging' instead of 'difficult' or 'annoying' is seen as more positive and professional.
These forms derive from the Old English present participle (-ende) and past participle (-ed/-en).

FAQ (8)
Yes! If you say `He is boring`, you are describing his personality—he makes other people feel bored. If you say `He is bored`, you are describing his current feeling.
Yes, you can use `very`, `quite`, `extremely`, or `really` with participial adjectives (e.g., `very interested`). This is a good way to tell them apart from verbs.
Some do not. For example, we use `scary` more often than `scaring`, though `scared` is common for the feeling.
Because `tired` is your feeling. `Tiring` would mean you are the one making other people sleepy!
No, `fun` is a regular adjective. We don't say `funned` or `funning` in this way.
Both are -ed adjectives, but `exhausted` is much stronger. It means `extremely tired`.
No. In English, -ing adjectives describe the source. If you want to use a verb for a feeling, you'd use the continuous tense: `I am hurting` (not a participial adjective).
It can be a verb (`This is interesting me`), but it is much more commonly used as an adjective.
