'agatize' originates from the word 'agate', which comes from the Greek word 'achates', referring to a river in Sicily where agates were found.

'agate' transformed from the Greek word 'achates' to the Latin 'achates', and eventually became the modern English word 'agate'.

Initially, it referred to the stone 'agate', but over time it evolved to mean the process of becoming agate-like.
