'coagulation' originates from Latin, specifically the word 'coagulatio', where 'co-' meant 'together' and 'agere' meant 'to drive'.

'coagulatio' transformed into the Old French word 'coagulation', and eventually became the modern English word 'coagulation'.

Initially, it meant 'the act of driving together', but over time it evolved into its current meaning of 'the process of a liquid changing to a solid or semi-solid state'.
