Formal address and protocol
In English-speaking countries, the wife of a foreign dignitary is called Madame (note final 'e') in direct address and formal correspondence, rather than the equivalent word in the person's native language (Señora, Frau etc.). However, in other contexts, it traditionally refers to the female head of a brothel.
