There’s a mistake my students sometimes make that can be funny, or kind of embarrassing. So I’ve asked along an embarrassing version of myself to demonstrate.

I’m very interesting. Ooooo. Did I say that? How embarrassing!

What I could say is ‘I’m very interested’. ‘Interesting’ and ‘interested’ are both adjectives, so what’s the difference?

This baseball game is really interesting.

We use ‘interested’ to say how we feel. We use ‘interesting’ to describe the person or thing that causes the feeling. So an interesting speaker, an interesting creature, an interesting book.
Notice that ‘interesting’ doesn’t mean important or big. It can in some languages, but not English. Very interesting. We can be interested in a business proposition.

Now something else. There are other adjectives that follow a similar pattern. Let’s look at one.
