Definition & Meaning of "the nose knows"in English

What is the origin of the proverb "the nose knows" and when to use it?

The origin of the proverb "the nose knows" is unclear, but it likely stems from the idea that a person’s sense of smell can often detect things that are not immediately visible or obvious. The saying suggests that intuition or instinct, much like the nose detecting subtle scents, can often reveal truths or insights that may not be apparent at first glance. Over time, the proverb has been used to highlight the importance of relying on one’s senses, especially intuition, to understand situations or uncover hidden details.
