A representative of the Pope who is sent to a foreign country to manage diplomatic relations.
The nuncio delivered a message from the Vatican to the local government.
Nuncio is derived from the Latin "nuntius" (meaning messenger) and the suffix "-o" (a common ending in Latin for nouns). The word "nuncio" refers to a messenger, particularly one who brings news or messages, often in a formal or official capacity.
Think of a 'messenger' ('nuntius') bringing important news — that's what a nuncio does.
