Questions & Answers about Jag har arton nya meddelanden.
Why is the word for "new" written as nya instead of just ny?
In Swedish, adjectives change to match the noun they describe. Because meddelanden (messages) is plural, you must use the plural form of the adjective, which adds an -a to make nya. If the noun were singular, you would use ny for an en-word or nytt for an ett-word.
What is the singular form of meddelanden, and how does its plural work?
The singular form is ett meddelande (a message). In Swedish, when an ett-word ends in a vowel, you generally make it plural by simply adding an -n to the end. That gives us meddelanden for "messages".
Doesn't the -en ending usually mean "the", like in bilen (the car)? Why is this translated as "messages" and not "the messages"?
This is a very common beginner trap! While -en does mean "the" for singular en-words, here it is just the natural result of adding the plural -n to the base word meddelande. It means "messages" in general. If you wanted to say "the messages" (definite plural), you would add an extra -a to make it meddelandena.
