Do languages and nationalities need capital letters?
A short introduction can be grammatically clear but still need an editing pass. Check the names of languages and nationality words wherever they appear, not just at the start.
Professor Scott MendozaThe short answer
In English, names of languages and nationality words begin with capital letters: “I study Korean” and “a Spanish teacher.” Ordinary subject names such as history and biology usually stay lowercase inside a sentence.
Capitalize the name, not every word around it.
Korean names a language in I study Korean. Spanish describes nationality in my Spanish neighbor. Both keep their initial capitals. In I study English and biology, English is a language name, but biology is an ordinary subject name. These are sentence-style examples, not headings or official course titles.
The same capital in different positions
I study Korean after work.
My Spanish neighbor is a nurse.
I study English and biology.
Use an initial capital, not an all-capitals word: English, rather than ENGLISH, in ordinary running text.

Which sentence correctly writes the language name in ordinary text?
I study Korean after work.Korean begins with K because it names a language. After and work are ordinary words here; this is not a title.
The neighbor is Spanish. Which sentence capitalizes the nationality adjective correctly?
My Spanish neighbor is a nurse.Spanish keeps its capital S. Neighbor and nurse are common nouns and stay lowercase inside this sentence.
You are listing subjects in a normal sentence, not giving official course titles. Which version fits?
I study English and biology.English is a language name. Biology is an ordinary subject name here, so it stays lowercase. A formal course title could use different capitalization.
Put it into practice
Edit a short club introduction.
Change only the capitalization. Keep the words and meaning. This is an ordinary sentence, not a heading or formal course title.
My korean friend studies spanish and history.
See a model answer
My Korean friend studies Spanish and history.
The edit keeps the original facts and changes only k to K and s to S. It does not claim that nationality determines the language someone studies.
A little more clarity
Common questions
A few useful details before you move on.
Does English need a capital in the middle of a sentence?
Yes. Its initial capital belongs to the language name, not just to the start of a sentence.
We speak English at the club.
Does Korean always mean the Korean language?
No. It can name a language or describe nationality or origin. Read the sentence to understand its role; the initial K stays capitalized in these uses.
My Korean friend studies Spanish.
Take it into your day
Keep initial capitals on language and nationality names. Do not spread capitals to ordinary nearby words.
