Ikke klandre ham.

It is a negative command or prohibition. In English, this is the kind of sentence that starts with Don’t ...

So the pattern here is basically:

Ikke + verb + object

Examples:

• Ikke gå! = Don’t go!
• Ikke rør den! = Don’t touch it!
• Ikke klandre ham. = Don’t blame him.

Because Norwegian usually leaves out the subject in commands.

Just like English says Stop! instead of You stop!, Norwegian normally says:

• Kom! = Come!
• Vent! = Wait!
• Ikke klandre ham. = Don’t blame him.

The you is understood from context.

In short negative commands, Norwegian normally puts ikke before the verb.

So:

• Ikke snakk så høyt. = Don’t speak so loudly.
• Ikke glem det. = Don’t forget it.
• Ikke klandre ham.

This is the normal and natural word order for this kind of sentence.

Here it is functioning as the command form.

For many Norwegian verbs, the imperative is shorter than the infinitive:

• å snakke → snakk!
• å vente → vent!

But some verbs keep a form that looks the same as the infinitive, especially when a shortened form would sound awkward. That is what happens here with klandre.

So in this sentence, klandre means blame! in the sense of a command.

Because ham is the object form of han.

• han = he (subject form)
• ham = him (object form)

Compare:

• Han kommer. = He is coming.
• Jeg ser ham. = I see him.
• Ikke klandre ham. = Don’t blame him.

A useful shortcut:

• if the person is doing the action, use han
• if the person is receiving the action, use ham

Not always. In everyday spoken Norwegian, many people use han where traditional written Bokmål has ham.

So you may hear:

• Ikke klandre han.

But in standard writing, ham is still completely correct, and it can sound a bit more formal or traditional.

So for a learner:

• ham is good to know for writing
• han in object position is common in speech

It is a real and correct word, but it can sound a bit formal, literary, or serious.

In everyday speech, Norwegians will often use other expressions, such as:

• Ikke skyld på ham. = Don’t blame him.
• Du kan ikke legge skylda på ham. = You can’t put the blame on him.

So klandre is useful to recognize, but it is not always the most casual everyday choice.

Not in normal modern Norwegian.

The natural order is:

• Ikke klandre ham.

Putting ikke later, as in Klandre ham ikke, sounds very old-fashioned, literary, or unnatural to most learners.

So the safe pattern is:

Ikke + verb + object

Because Norwegian usually keeps normal verb + object order in simple commands.

So:

• Les boka. = Read the book.
• Hjelp ham. = Help him.
• Ikke klandre ham.

The verb comes first, and the object follows it.

No. A period is perfectly fine.

• Ikke klandre ham. sounds like a calm instruction or advice.
• Ikke klandre ham! sounds stronger or more emotional.

So the punctuation changes the tone a little, but both are possible.
