The term “compass” comes from the Old French word “compas,” which means “circle” or “measure.” This is derived from the Latin word “compassus,” which combines “com-” meaning “together” and “passus,” meaning “a step” or “pace.”

1. Proto-Indo-European (PIE)

The PIE root “*ped-” means “foot” or “step.”

2. Latin

From the PIE root, the Latin word “passus” developed, meaning “step” or “pace.” The prefix “com-” (together) was combined with “passus” to form “compassus,” meaning “a measure” or “a circle.”

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

The Latin term “compassus” evolved into Old French “compas,” meaning “circle,” “measure,” or “a pair of compasses used for drawing circles.”

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

The Old French “compas” was adopted into Middle English as “compas,” meaning “a device for drawing circles” and later “a navigational instrument for finding direction.”

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

The term “compass” evolved into its current form and pronunciation, retaining the meanings of “a device for drawing circles” and “a navigational instrument.”

Phonetic Evolution

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