What fourteen languages do the Gallagher girls speak?

The Gallagher Girls, characters from Ally Carter's "Gallagher Girls" series, don't actually speak fourteen languages. While they are highly trained spies, the series focuses more on their skills in espionage, hand-to-hand combat, and other spy-related abilities.

However, there are hints in the series that they do learn some foreign languages. For example:

* Cammie Morgan, the protagonist, is shown to be fluent in French. She uses her French skills to infiltrate a French embassy and to communicate with a French spy.

* Other Gallagher Girls are shown to be proficient in other languages. We see them using Spanish, German, and Italian at different points in the series.

While the exact number of languages they speak isn't explicitly stated, it's safe to assume that they are proficient in a variety of languages to aid them in their missions.
