'coagulable' originates from Latin, specifically the word 'coagulabilis,' where 'coagulare' meant 'to cause to curdle or clot.'

'coagulabilis' transformed into the French word 'coagulable,' and eventually became the modern English word 'coagulable' through Middle English.

Initially, it meant 'capable of curdling or clotting,' and this meaning has largely remained the same in modern usage.
