Learn Swedish: Mannen pekar på huset med käppen. - The man points at the house with the cane.

In Swedish, the verb pekar (points) naturally pairs with the preposition på to mean points at. Prepositions rarely translate perfectly one-to-one between languages, so it is best to memorize pekar på as a set phrase.

Why does the sentence use käppen (the cane) instead of his cane?

Swedish frequently uses the definite form (here, käppen) instead of a possessive pronoun like sin or hans when it is obvious from the context who the item belongs to. This is especially common with body parts, clothing, and everyday personal items.

What is the base form of käppen?

The base word is käpp, which means cane or walking stick. Because the definite form here is käppen, you can easily tell it is an en-word (en käpp).

Does med käppen describe how the man points, or does it describe the house?

Grammatically, it is ambiguous, exactly like the English translation. The phrase med käppen could mean he is using the cane as a tool to point, or that he is pointing at a house that somehow features a cane. Common sense tells us it is the tool he is using.
