In English, we often say things like “Reading is fun” or “Swimming is difficult.” That “-ing” turns the verb into a noun—a process called nominalization. In Japanese, one of the ways to do this is with の. の is used to turn verbs into nouns when you’re describing something you see, hear, feel, or experience. It’s a simple and natural way to describe actions like they’re things.

How to Use It
Use の when you’re describing something that is being perceived or is closely tied to emotion or action in the moment. It’s commonly used with verbs like 見る (to see), 聞く (to hear), 待つ (to wait), or やめる (to stop). This makes it perfect for sentences like “I saw someone playing guitar” or “Let’s stop smoking.”
