'amniorrhea' originates from Greek, specifically the word 'amnion,' where 'amnion' meant 'membrane around the fetus,' and 'rhoia' meant 'flow or discharge.'

'amnion' combined with 'rhoia' in Greek to form 'amniorrhea,' which was adopted into modern medical terminology.

Initially, it meant 'discharge of amniotic fluid,' and this meaning has remained consistent in medical contexts.
