gut
"Gut" is a versatile word with several common meanings. It can be a noun referring to parts of the body, an adjective describing a deep instinctive feeling, or a verb meaning to remove the inside of something. Here are the most useful senses.
Your gut is the tube inside your body that processes food — basically your stomach and intestines. When people say 'my gut hurts', they mean they have a stomach ache. You might also hear 'gut health', which refers to how well your digestive system is working.
