Etymology

diamond = dia<through> + mond<hard>

  • dia<through>: From Greek dia-, meaning "through" or "across."
  • mond<hard>: Derived from Late Latin adamas (via Old French diamant), meaning "unconquerable" or "hardest metal," referring to the stone's extreme hardness.

Etymology Origin:
The word "diamond" traces back to the Greek adamas (unbreakable), which entered Latin as adamas and later Old French as diamant. The Greek prefix dia- (through) was likely reinterpreted in Medieval Latin, merging with -mond (from adamas) to form diamant. The term reflects the stone's legendary hardness, symbolizing invincibility in ancient cultures.
