Learn Danish: Hvor er mit pas? - Where is my passport?

In Danish, the word for "my" changes depending on the gender of the noun. Because pas (passport) is an et-word (neuter gender), you must use mit. If it were an en-word (common gender), like bil (car), you would use min.

Why is it just pas after mit, and not the definite form passet?

When you use a possessive word like mit (my) or dit (your) in Danish, the noun that follows it must stay in its basic, indefinite form. So you say mit pas (my passport), never mit passet.

How do you pronounce the word Hvor?

The h is completely silent! You just pronounce the "vor" part. It sounds like the English word "war", but starting with a "v".

How would I say "Where are my passports?" if I have more than one?

You would change the possessive word to the plural form, mine, and say: Hvor er mine pas? The noun pas happens to look exactly the same in the singular and the plural. In the original sentence, we only know it means a single passport because we see mit instead of mine.
