🌳Etymology

Origin

This phrase originated from the practical use of the human thumb as a crude measuring tool, since the thumb is approximately one inch in length. Over time, it evolved to denote any rough, practical guideline or standard that is approximate rather than precise or officially established.

Breakdown

rule (a principle or standard) + of (indicating possession or relationship) + thumb (the shortest, thickest digit of the hand, historically used as an informal measuring unit).
