What is the major language of California?

While California is a very diverse state with many languages spoken, the major language of California is English.

However, it's important to acknowledge that:

* Spanish is the second most spoken language in California, with a significant presence due to its history and large Hispanic population.

* Many other languages are spoken in California, reflecting its diverse immigrant communities. These include Mandarin Chinese, Vietnamese, Tagalog, Korean, and many more.

So, while English is the major language, California is a multilingual state with a rich tapestry of languages spoken by its residents.
