Word History

Etymology

Middle English achates, accate, agaten, borrowed from Anglo-French & Latin; Anglo-French achate, agathe, borrowed from Latin achātēs, borrowed from Greek achā́tēs, of uncertain origin

Note: According to Theophrastus and Pliny, the stone was named after a river in Sicily. Modern etymologists seem disinclined to believe this and suggest that the river was named after the stone. The voiced stop in the medieval French forms, which has become the dominant form in Modern French and English, begins to appear in Medieval Latin, and may be owed to Medieval Latin agapis, a word of obscure origin used for both the agate and lapis lazuli; it has been suggested that agapis is itself a distortion of achates (crossed with Latin lapis "stone"?), though this is far from clear.
