hysterical (adj.)

nervous disease, 1801, coined in medical Latin as an abstract noun from Greek hystera "womb," from PIE *udtero-, variant of *udero- "abdomen, womb, stomach" (see uterus). Originally defined as a neurotic condition peculiar to women and thought to be caused by a dysfunction of the uterus. With abstract noun ending -ia. General sense of "unhealthy emotion or excitement" is by 1839.

"female organ of gestation, womb," late 14c., from Latin uterus "womb, belly" (plural uteri), from PIE root *udero- "abdomen, womb, stomach" (source also of Sanskrit udaram "belly," Greek hystera "womb," Lithuanian vėderas "sausage, intestines, stomach, lower abdomen," Old Church Slavonic vedro "bucket, barrel," Russian vedro).
