dyamaunt (Middle English)
Where does "dyamaunt" come from?
The Middle English noun 'dyamaunt' entered the language as a borrowing from Old French 'diamant'[1]. This Old French form descended from Late Latin 'diamās', which derived from Latin 'adamās'[1]. The Latin term ultimately traces back to Ancient Greek 'ἀδάμας'[1], meaning invincible[3]. Along its linguistic journey, the word shifted from denoting an indomitable quality or substance to designating the valuable gemstone, and it stands as a doublet of 'adamant'.
Open questions
- The Late Latin form may have arisen through a metathesis of adimas. [2]
- While traditionally derived from Greek elements meaning not and conquer, the Ancient Greek term may instead be a Semitic borrowing adapted by folk etymology. [3] [4]
