Learn Finnish: Tuon kauniin muotokuvan maalasi hiljainen mies. - That beautiful portrait was painted by a quiet man.

In English, we often use the passive voice to put the focus on the object ('that beautiful portrait'). However, Finnish passive sentences typically drop the 'doer' (the agent) entirely. To focus on the portrait and still mention who painted it, Finnish keeps the verb active (maalasi) but moves the object to the front of the sentence. This creates an Object-Verb-Subject (OVS) word order.

Why do the first three words (tuon kauniin muotokuvan) all end in -n?

They make up the total object of the sentence. Even though they appear at the very beginning, which is usually the subject's spot, the -n ending (the accusative or genitive case) signals that 'that beautiful portrait' is the thing being painted, not the one doing the painting. All modifiers like tuon and kauniin must match the case of muotokuvan.

How can you tell grammatically that hiljainen mies is the subject, despite being at the end of the sentence?

The phrase hiljainen mies is in the nominative case (the basic dictionary form). If the man were the object, the phrase would need an object marker like an -n ending (hiljaisen miehen) or the partitive case. Because it is in the nominative, we know the man is the subject doing the action.

How does the emphasis change if I use standard word order: Hiljainen mies maalasi tuon kauniin muotokuvan?
