ultra
UK: ˈʌltrə | US: ˈʌltrə
adj. beyond what is usual or ordinary; extreme
n. an extremist or radical person
The word ultra originates from Latin ultra, which literally means "beyond" or "on the other side." It was adopted into English in the early 19th century, initially used in scientific and political contexts to denote extremes (e.g., ultraviolet, ultraconservative). Over time, it evolved into a standalone adjective and noun, often describing radical positions or excessive behavior. The simplicity of its structure—no prefix or suffix—makes it a versatile term for emphasizing extremity.
