'liquid-based' originates from the English word 'liquid' combined with the suffix '-based', where 'liquid' meant 'a substance that flows freely but is of constant volume' and '-based' indicates the primary component or foundation.

'liquid' changed from the Latin word 'liquidus' and eventually became the modern English word 'liquid'.

Initially, 'liquid' meant 'fluid or flowing', but over time it evolved into its current meaning of 'a substance that flows freely but is of constant volume'.
