However, it's important to note that:
* Native Californian languages were also spoken. While the mission aimed to convert indigenous peoples to Christianity and assimilate them into Spanish society, many Native Californians still maintained their own languages and customs.
* Some indigenous languages were used alongside Spanish. Missionaries often used indigenous languages to communicate with the natives, and some indigenous languages were even incorporated into religious practices.
* Over time, Spanish evolved into Californian Spanish which incorporated elements of indigenous languages and culture.
In short, while Spanish was the dominant language, Mission Carmel was a multilingual space, with various Native Californian languages also being used.
