'hysteria' originates from Greek, specifically the word 'hystera,' meaning 'womb,' reflecting the ancient belief that the condition was related to the uterus.

'hystera' transformed into the Latin word 'hysteria,' and eventually became the modern English word 'hysteria' through Middle English.

Initially, it meant 'a condition thought to be caused by disturbances in the uterus,' but over time it evolved into its current meaning of 'extreme emotional excitement or disturbance.'
