'liquid' originates from Latin, specifically the word 'liquidus,' where 'liqu-' meant 'fluid' or 'flowing.' 'Associated' comes from Latin 'associatus,' meaning 'joined with.'

'liquidus' transformed into the Old French word 'liquide,' and eventually became the modern English word 'liquid.' 'Associatus' evolved into the Old French 'associer,' leading to the modern English 'associate.'

Initially, 'liquid' meant 'fluid or flowing,' and this meaning has largely remained the same in modern usage. 'Associated' originally meant 'joined with,' which has evolved to mean 'connected or related to.'
