The term “rule” comes from the Latin word “regula,” which means “straight stick” or “regulation.” This is derived from the Latin root “regere,” meaning “to guide” or “to govern.”

1. Proto-Indo-European (PIE)

The PIE root “*reg-” means “to move in a straight line” or “to direct.”

2. Latin

From the PIE root, the Latin word “regere” developed, meaning “to guide” or “to govern.” The noun “regula” combines “regere” with the suffix “-ula,” indicating a tool or instrument, thus meaning “a straight stick” or “a guideline.”

3. Old French (c. 9th to 14th century CE)

The Latin term “regula” evolved into Old French “reule,” meaning “a rule” or “a principle.”

4. Middle English (c. 11th to 15th century CE)

The Old French “reule” was adopted into Middle English as “reule” or “rule,” meaning “a principle or regulation governing conduct.”

5. Modern English (from 15th century CE to present)

The term “rule” evolved into its current form and pronunciation, retaining the meaning of “a prescribed guide for conduct or action” or “a standard.”

Phonetic Evolution

Over time, the pronunciation of “rule” has remained relatively stable, transitioning from the Old French “reule” to the Modern English “rule.”
