Fascinated BY or WITH? Difference Explained (14 Examples)

Prepositions are important building blocks in English. They may be small words, but they often come with a subtle difference in meaning for certain words that they come after. In this article, we’ll go through the differences between “fascinated by” and “fascinated with.”

What Is The Difference Between “Fascinated By” And “Fascinated With”?

“Fascinated by” should be used when talking about something that grabs our attention while not necessarily taking part in it (“fascinated by world-class athletics”). “Fascinated with” should be used when talking about a more direct engagement with an activity (“fascinated with computer science”).

What Is The Difference Between "Fascinated By" And "Fascinated With"?

Generally, it’s possible to use “fascinated by” in the same way that we use “fascinated with,” meaning that we’re talking about something we’re actively participating in grabbing our attention.

However, it’s not possible to be “fascinated with” things that we’re “fascinated by,” as the “with” implies a direct relationship and engagement with the thing.

What Preposition Comes After Fascinated?

Let’s look at some of the prepositions choices that come after fascinated as a word and see why the meaning is affected in such a way.


We use “fascinated with” to talk about things that we’re taking part in. Usually, we will talk about a hobby or something similar that grabs and maintains our attention.

  • I’m fascinated with computers. (This means you work with computers and enjoy learning about them).
  • I’m fascinated with rocks. (This means you have a hobby collecting or studying rocks).

A direct relationship is always implied when using “with.”


We use “fascinated by” to talk about things that we’re viewing from the outside. These things may still grab our attention, but we don’t have to take part in them to be fascinated.

  • I’m fascinated by computers. (How computers work is a fascinating idea, but we might not know a thing about them or may not want to learn more).
  • I’m fascinated by rocks. (We might think rocks look cool or have interesting histories, but again, we’re not interested in getting involved.

Generally, there aren’t any other prepositions that we would use after “fascinated,” so we can’t explain anymore.

What Does “Fascinated By” Mean?

We’ve already touched on what “fascinated by” means when we use “by” as a preposition, but let’s go a bit further and give you something to refer back to when the time comes.

“Fascinated by” means that something grabs and holds your interest. Generally, you don’t have a direct relationship or reason to get involved with the interest, and you’re more than happy to stay as an outside observer, enjoying it but not getting involved.

It’s common for people to be “fascinated by” world-class sports, where they won’t ever actually play at a high enough level, but they love to watch it because it brings them joy. Some people don’t even play the sports they watch, which works even better when explaining how to use “fascinated by.”
