Mexico DF is the word for Mexico City in Spanish

I think that is false because they either say Mexico or el DF referring to Districto Federal, correct? They never say Mexico DF do they?

Don't forget the accent = México

Because México can be the country, you will hear often México, DF to refer to the city. You will also hear: "la ciudad de México."

Therefore, I would say "true."

You are correct. In Spanish, the proper term for Mexico City is "Ciudad de México" or simply "México." The abbreviation "DF" stands for "Distrito Federal," which was the official name of Mexico City until 2016. However, people seldom refer to Mexico City as "DF" nowadays. In 2016, the Federal District was abolished and transformed into a federative entity called "Ciudad de México" (Mexico City). Therefore, it is more accurate to use these terms to refer to the capital of Mexico in Spanish.
