How do you capitalize in Finnish? Proper nouns? Only the first word?

See a translation

- The first word in a sentence
- Proper nouns/names of people and places.
- Unlike English, however, you don't capitalize the names of languages. For example, you will write Suomi (Finland) but you will write suomi (the Finnish language). You also won't capitalize the word Finnish when it is an adjective describing things relating to the country (same for other countries as well).
- Another thing I've discovered is that, when it comes to names of songs, books, movies, etc, you often don't capitalize every word like you do in English (unless there is a proper noun in the title, of course). You will simply capitalize the first word.


I feel like I'm missing some other rules, too, but those are the ones I could come up with.
