While French is the dominant language, it's worth noting that:
* Occitan (also known as Provençal) was historically spoken in the region. It is still spoken by some older people, though its use has significantly decreased in recent decades.
* Arabic is spoken by a significant number of immigrants, primarily from North Africa.
* English is widely understood, especially in tourist areas and businesses catering to international visitors.
Overall, while French is the primary language of Bordeaux, you'll likely encounter a mix of other languages depending on the context.
