'syntax-based' originates from the Greek word 'syntaxis,' where 'syn-' meant 'together' and 'taxis' meant 'arrangement.'

'syntaxis' transformed into the Latin word 'syntaxis,' and eventually became the modern English word 'syntax' through Middle English, combined with 'based' to form 'syntax-based.'

Initially, 'syntax' meant 'arrangement of words,' and this meaning has largely remained the same in modern usage.
