Do you capitalize the word Spanish when referring to language?

Yes, you capitalize "Spanish" when referring to the language.

Here's why:

* Languages are proper nouns: They are specific names of things, just like names of people or places.

* Consistency with other languages: We capitalize the names of other languages too, such as English, French, German, etc.

Example:

* "I am learning Spanish."

However, if you are referring to people from Spain, you would use lowercase:

* "I met some Spanish people on vacation."
