'gut-feeling' originates from the English word 'gut,' which refers to the stomach or belly, and 'feeling,' which refers to an emotional state or reaction.

'gut-feeling' combines the words 'gut' and 'feeling' to describe an instinctive reaction, often felt in the stomach area, and eventually became a common English expression.

Initially, it referred to a physical sensation in the stomach, but over time it evolved into its current meaning of an instinctive or intuitive feeling.
