'constipative' originates from Latin, specifically the word 'constipare,' where 'con-' meant 'together' and 'stipare' meant 'to press or pack tightly.'

'constipare' transformed into the French word 'constiper,' and eventually became the modern English word 'constipate,' from which 'constipative' is derived.

Initially, it meant 'to press or pack tightly,' but over time it evolved into its current meaning of 'causing constipation.'
