Hun kysser fotografiet.

Kysse is the infinitive, meaning to kiss.

In the sentence, you need the present tense, so it becomes kysser:

• å kysse = to kiss
• hun kysser = she kisses / she is kissing

In Norwegian, the present tense is very simple because the verb does not change for different persons:

• jeg kysser
• du kysser
• hun kysser

So kysser works for I, you, she, and so on.

It can mean either one, depending on context.

Norwegian often uses the simple present where English might use either:

• She kisses the photograph
• She is kissing the photograph

So hun kysser fotografiet can describe:

• a general action, or
• something happening right now

Context tells you which meaning is intended.

Because fotografiet is the definite singular form, meaning the photograph.

The basic noun is:

• et fotografi = a photograph

When you make it definite, Norwegian usually adds the definite article as an ending on the noun:

• fotografi → fotografiet

So:

• et fotografi = a photograph
• fotografiet = the photograph

In Norwegian, the is usually built into the noun as a suffix.

English uses a separate word:

• the photograph

Norwegian usually uses an ending instead:

• fotografiet

That -et ending is what makes the noun definite here.

This is a very common feature of Norwegian nouns.

You generally have to learn the noun together with its article:

• et fotografi

That tells you fotografi is a neuter noun in Bokmål.

This matters because the gender affects forms such as the definite singular:

• et fotografi
• fotografiet

A good habit is to memorize nouns with their article from the beginning, not by themselves.

The sentence follows the basic pattern:

Subject + Verb + Object

• Hun = subject
• kysser = verb
• fotografiet = object

So it works very much like English:

• She kisses the photograph

This is a very normal Norwegian main clause.

Yes. That would mean She kisses a photograph.

The difference is:

• Hun kysser fotografiet = She kisses the photograph
• Hun kysser et fotografi = She kisses a photograph

So the choice depends on whether you mean a specific photograph or just one photograph.

A rough guide is KYSS-er, but the sound written y is important: it is not the same as English y.

The Norwegian y is a rounded vowel, similar to:

• French u
• German ü

Also, in many varieties of Norwegian, the k before y is pronounced with a soft kj-like sound rather than a hard English k.

So kysser may sound difficult at first, even though it looks simple on paper.

In a sentence like this, yes: hun means she.

It is the third-person singular pronoun for a female person.

Here it is capitalized only because it comes at the beginning of the sentence. In the middle of a sentence, it would normally be written hun, not Hun.
