A snore is the sound someone makes when they're asleep and not breathing properly. It's usually loud and can be annoying.
When people are talking about snoring, they often mention it as a problem their partner or roommate has at night. They might say, "Sorry to wake you up, but I couldn't sleep through your snoring!" Snoring is also used in a more lighthearted way when describing someone's ability to eat a lot of food. For example, "I can eat as much pizza as I want and still not get tired; I'm a total snorer!" This usage isn't about sleeping at all but rather implies that the person has a big appetite or can put away lots of food without getting full quickly.
The act of snoring, and the noise produced.
To breathe during sleep with harsh, snorting noises caused by vibration of the soft palate.
