The word "hysterofrenic" refers to a condition where someone experiences both hysteria and delirium. It is spelled with a "y" in the first syllable to denote the word's origins from the Greek root "hystera," meaning "uterus." The second syllable "frenic" comes from the Greek "phren," meaning "mind," and is spelled with an "e" instead of an "i" because of the letter's transliteration from Greek to English. The IPA pronunciation of "hysterofrenic" is hɪstərəuˈfrenɪk.
Arresting an hysterical attack, noting certain areas pressure upon which has this effect.
