He maksoivat miljoona euroa.

No. In standard Finnish, he means they. The English-looking spelling is just a coincidence.

• English he = Finnish hän
• English they = Finnish he

So He maksoivat... starts with They paid...

Because the subject he is third-person plural, and the verb has to match it.

• hän maksoi = he/she paid
• he maksoivat = they paid

So maksoivat is the correct past-tense plural form for he.

The dictionary form is maksaa = to pay.

In the past tense, this verb uses the stem maksoi-, and then Finnish adds -vat for third-person plural:

maksaa → maksoi → maksoivat

That is why it is maksoivat, not maksaivat.

After an exact number, Finnish usually puts the counted noun in the singular partitive.

So you get:

• kaksi euroa = two euros
• sata euroa = one hundred euros
• miljoona euroa = one million euros

Even though English uses a plural noun, Finnish uses euroa here.

Because miljoona euroa is the normal way to express an exact amount here: miljoona + singular partitive euroa.

You may see miljoonan euron in a different structure, for example:

• miljoonan euron talo = a one-million-euro house

But in this sentence, miljoona euroa is the normal form.

It functions as the amount paid. For a learner, the most useful thing is to remember the pattern:

maksaa + amount

For example:

• maksaa kymmenen euroa
• maksaa sata euroa
• maksaa miljoona euroa

If the sentence is negative, the amount phrase changes:

• He eivät maksaneet miljoonaa euroa = They did not pay one million euros

So the positive sentence uses miljoona euroa, but the negative one uses miljoonaa euroa.

Yes. Finnish word order is flexible.

He maksoivat miljoona euroa is the most neutral order: subject + verb + amount

You can also move things for emphasis, for example:

Miljoona euroa he maksoivat

That puts more focus on the amount. But the original order is the best basic pattern for learners.

Usually not in a simple isolated standard sentence like this. In Finnish, first- and second-person pronouns are often omitted, but third-person subjects are normally expressed unless the context already makes them obvious.

So He maksoivat miljoona euroa is the safe standard form.

Very often, yes. In casual spoken Finnish, many speakers would say:

Ne maksoi miljoona euroa

That is more colloquial. The sentence He maksoivat miljoona euroa is standard Finnish, especially suitable for writing or careful speech.

It is pronounced roughly heh, with a short Finnish e sound. It is not pronounced like English hee.

That often surprises English speakers, because the spelling looks familiar even though the word means something different.
