The term “coin” comes from the Old French word “coigne,” which means “corner” or “wedge.” This is derived from the Latin word “cuneus,” meaning “wedge.”

1. Proto-Indo-European (PIE)

The PIE root “*keu-” means “to swell” or “to vault,” which evolved to imply a wedge shape.

2. Latin

From the PIE root, the Latin word “cuneus” developed, meaning “wedge.” The term was used to describe wedge-shaped objects, including dies used for stamping metal.

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

The Latin term “cuneus” evolved into Old French “coigne,” meaning “corner” or “wedge.” It was also used to refer to the die used to stamp coins.

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

The Old French “coigne” was adopted into Middle English as “coin,” meaning “a die for stamping money” and later “a piece of money.”

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

The term “coin” evolved into its current form and pronunciation, referring to a piece of metal stamped and issued by governmental authority as money.
