Learn Swedish: Hon har tolv äpplen. - She has twelve apples.

In Swedish, nouns form plurals in different ways depending on whether they are en or ett words. Because äpple is an ett word that ends in a vowel (ett äpple), you simply add -n to the end to make it plural, giving us äpplen.

Doesn't the verb har need to change because the subject is hon (she)?

No, and this is great news for learners! Unlike English, which changes verbs depending on the person (I have, she has), Swedish verbs stay exactly the same for everyone. It is jag har (I have), hon har (she has), and vi har (we have).

I always mix up hon (she) and han (he). How can I remember the difference?

This is a very common hurdle for beginners! A good trick is to focus on the pronunciation. The vowel in hon sounds a lot like the short vowel in the English word "book" or "foot". On the other hand, the vowel in han is a short, open sound like the "a" in "father".
