This means that:
* All official documents and communications are produced in both English and French.
* Meetings and conferences are typically conducted in both languages with simultaneous interpretation.
* Personnel working at NATO headquarters are expected to be proficient in at least one of these languages.
While English and French are the primary working languages, other languages are also used within NATO, especially when dealing with specific countries or situations. For example, German, Italian, Spanish, and Turkish are sometimes used in meetings and communications.
Therefore, while English and French are the dominant languages, NATO operates in a multilingual environment, reflecting its diverse membership.
