Fields have eyes, and woods have ears.

Even places that seem empty or secluded may contain observers or people who can overhear. The saying warns that private words and actions can become known beyond the intended audience.

Its imagery is figurative, treating fields and woods as though they could see and hear. It encourages discretion rather than assuming that open country, a remote setting, or apparent solitude guarantees secrecy.

Use it as a caution before discussing sensitive matters or acting covertly in a place thought to be deserted. It suits a serious or lightly figurative reminder that privacy can be less secure than it appears.
