Roots and History

The origin of this idiom is not entirely clear, but it has been in use since at least the 18th century. One theory suggests that the phrase comes from the idea of spies or informants who could observe events without being seen, much like a fly on a wall. Another theory suggests that the phrase comes from the idea of a silent observer or eavesdropper who is unnoticed by those around them. Either way, the idiom has become an enduring metaphor for someone who is watching events unfold without being actively involved.
