Learn Icelandic: Mín unga drottning les bókina. - My young queen reads the book.

The possessive pronoun mín (my) comes right before it. Possessive pronouns act as triggers that force the following adjective into its weak form. Because drottning (queen) is a feminine singular noun in the nominative case, the weak ending is -a, giving us unga.

I learned that possessive words usually go after the noun. Why is mín at the beginning here?

Putting the possessive pronoun before the noun is perfectly correct, though it sounds a bit more formal, emphatic, or poetic than putting it after. Whenever you put the possessive first, remember that it triggers the weak adjective declension.

If we use the weak adjective form, shouldn't the noun have the definite article attached? Why is it just drottning?

That is a great catch! Usually, weak adjectives are paired with nouns that have the attached definite article. However, there is a special rule: when a possessive pronoun like mín comes before the noun, it blocks the definite article. The noun must stay indefinite, which is why we use drottning instead of drottningin.

What case is bókina in, and why?

It is in the accusative case because it is the direct object receiving the action of the verb les (reads). The word bók is a feminine noun, and to make it definite in the accusative case, we add the ending -ina to get bókina.
