This is a classic distinction in English that reveals a key pattern. Let's break it down and list other common cases.
-ed adjectives describe how someone feels. The emotion is received.
"I am bored." (Something is causing me to feel this way.)
-ing adjectives describe the thing or person that causes the feeling. The emotion is projected.
"This book is boring." (It causes boredom.)
1. Bored / Boring
She was bored during the lecture.
The lecture was boring.
2. Interested / Interesting
I am interested in history. (I feel interest.)
I find history interesting. (It causes interest.)
3. Excited / Exciting
The children are excited about the trip.
It will be an exciting adventure.
4. Tired / Tiring
I'm so tired today. (I feel fatigue.)
That hike was tiring. (It caused fatigue.)
5. Surprised / Surprising
We were surprised by the news.
The news was very surprising.
6. Confused / Confusing
He was confused by the instructions.
The instructions were confusing.
7. Frustrated / Frustrating
She felt frustrated with the slow progress.
The slow progress was frustrating.
8. Amused / Amusing
The audience was amused by the clown.
The clown's act was amusing.
9. Annoyed / Annoying

That buzzing sound is really annoying.
10. Disappointed / Disappointing

The movie's ending was disappointing.
11. Shocked / Shocking
We were shocked to hear he quit.
The sudden resignation was shocking.
12. Embarrassed / Embarrassing

It was an embarrassing moment.
Not all adjectives have both forms. Some common ones like happy, sad, angry only describe feelings.
Some -ing adjectives don't have a direct -ed partner for people. For example:
You can say a book is fascinating (causes fascination), but we usually say "I am fascinated" rather than "I am fascinate."
You can use them together: "The confused student read the confusing textbook."
Think of the -ed ending as related to the past participle, implying something was done to you.
Think of the -ing ending as related to the present participle, implying something is doing the action.
Test yourself: The [interested/interesting] student watched an [interested/interesting] documentary.
Answer: The interested student watched an interesting documentary.
Mastering this distinction will make your English sound much more natural and precise!
This is a different but very important structure that deals with nouns, not feelings. Let's clarify.
Specialized knowledge = Knowledge that is focused on a specific, narrow field.
Specialized here acts as an adjective (past participle) describing the noun knowledge. It means "the knowledge has been made specific."
It's the standard and correct phrase.
Example: "You need specialized knowledge in quantum physics to understand this paper."
Specializing knowledge = This is incorrect and not used. "Specializing" is a verb form (gerund/present participle) and doesn't work as an adjective for "knowledge." Knowledge itself cannot perform the action of "specializing."
The bored/boring pattern uses participial adjectives.
The specialized knowledge pattern uses a past participle as an adjective to modify a noun, often showing a passive state or a completed action.
Here are more common and useful examples for learners:
These imply the noun has been "acted upon" or is in a state resulting from an action.
1. Advanced / Advancing
Advanced technology (technology that has been developed to a high level).
Advancing army (an army that is moving forward). Here, "advancing" is an active -ing adjective.
2. Developed / Developing
A developed country (a country that has become industrialized/mature).
A developing nation (a nation that is in the process of developing).
3. Established / Establishing
An established company (a company that has been set up and is well-known).
An establishing business (awkward; we'd say "a start-up" or "a newly established business").
4. Required / Requiring
Required reading (reading that has been designated as necessary).
A task requiring skill (a task that needs skill). Here, it's a verb phrase, not a direct adjective.
5. Used / Using
A used car (a car that someone has used before).
A tool using electricity (a tool that uses electricity).
6. Written / Writing
A written exam (an exam that is conducted in writing).
A writing desk (a desk for the purpose of writing). This is a special "purpose" noun phrase.
7. Frozen / Freezing
Frozen food (food that has been frozen).
Freezing temperatures (temperatures that cause freezing).
8. Broken / Breaking
A broken window (a window that has been broken).
Breaking news (news that is breaking right now).
This is where confusion often happens.
Structure
Meaning
Example
-ing + Noun
Often describes the purpose or function of the noun.
A washing machine (a machine for washing).
-ed / Past Participle + Noun
Describes the current state or condition of the noun.
Washed clothes (clothes that have been washed).
More "Purpose" (-ing) Examples:
Cooking oil (oil for cooking)
Running shoes (shoes for running)
Sleeping bag (a bag for sleeping)
Reading glasses (glasses for reading)
Pattern
Example
Key Idea
Feelings (-ed vs. -ing)
I'm bored. vs. The movie is boring.
-ed = feels it; -ing = causes it
State (-ed / Past Participle)
specialized knowledge, used car, written exam
Noun has been [verb]ed / is in a completed state
Purpose / Function (-ing)
washing machine, cooking oil
Noun is used for [verb]ing
So, while specialized knowledge is correct and common, it belongs to a different family of structures than boring/bored. It's about the state of the knowledge (it has been made specific), not about how the knowledge feels or what it causes.
