Welcome to the voice of America's news words.

In Cuba, more than 20 American diplomats recently suffered unexplained health problems.

Sophisticated.

The diplomats reported injuries such as loss of hearing, headaches and confusion.

U.

S officials are investigating them as targeted attacks.

Whatever happened, these people happen as a result of some sophisticated technology that, quite frankly, is so sophisticated we don't understand it.

Sophisticated technology is highly developed and complex.

A sophisticated person has worldly experience and knows about fashion, art and culture.

Now you know what sophisticated means.
