Interested or Interesting - Using Participle Adjectives Correctly

Jane Lawson,  English Teacher at DailyStep EnglishHello, I'm Jane at DailyStep English.
This week I’m going to cover a really important grammar topic that you just have to know – whether you are taking exams such as IELTS or whether you just want to speak better English. So read and listen carefully, and don’t forget to take the quiz!  

Participle Adjectives – are they Interested or Interesting?

by Jane Lawson at

It is such a common mistake – and I hear it even from advanced learners! I’m talking about the confusion between present and past participle adjectives. For example, Interested and Interesting, Bored and Boring, Excited and Exciting.

Participle Adjectives in English- Interested or Interesting

But first – quick grammar check…. Do you know what a participle is?

It’s simple: all verbs have a present participle (verb + -ING) and a past participle, which in regular verbs is always VERB + -ED.

So, how can you use participle as adjectives? Let’s take a look:

1. This book is interesting.

2. I am interested in this book.

In sentence 1 the present participle INTERESTING describes the book

In sentence 2, the past participle INTERESTED describes how I feel about the book.

So, the rule is this:

The Present participle (- ING) describes a person or thing

The past participle (- ED) describes how you feel about a person or thing.

This is an easy rule to remember, so if you learn it, your English will immediately get much better.

Why is this? Because we can make participle adjectives out of so many verbs. Also, spoken and written English exams (such as IELTS, Cambridge First Certificate, Cambridge Proficiency and so on) ask you to say how you feel about things. So if you get these participle adjectives mixed up, you will lose marks in exams and people will misunderstand you when you speak.

**Always remember to learn the correct preposition, for example INTERESTED IN, WORRIED ABOUT, BORED WITH and so on.**

If you really want to impress your examinermake sure you use different ways of expressing the same thing. So in addition to sentences 1 and 2 above, you can also express the same ideas like this:

3. This book interests me. (note: the passive form of this is “I am interested in this book.”)

4. I find this book interesting(note: this means “I think that this book is interesting.”)

Here are some more examples of participle adjectives, showing their correct preposition:


Present participle

Past participle



excited about



relaxed  about



frightened of



bored with



worried about
