Rouva odottaa toimistossa.

Rouva is in the nominative case, which is the basic dictionary form of a noun. In this sentence, it is the one doing the action, so it is the subject.

• rouva = the lady / the woman / Mrs.
• odottaa = waits / is waiting
• toimistossa = in the office

So rouva is the person who is waiting.

Finnish does not have articles like English a, an, or the.

So rouva can mean:

• a lady
• the lady
• sometimes simply lady depending on context

You understand which one is meant from the situation, not from a separate article word.

Because the noun rouva is already stated, Finnish does not need a separate pronoun.

In English, you say The lady is waiting.
In Finnish, Rouva odottaa is enough.

Adding hän (she/he) would usually be unnecessary here unless you wanted extra emphasis or contrast.

Here, odottaa is the 3rd person singular present tense form: waits / is waiting.

This is one of those useful Finnish verbs where the infinitive and the 3rd person singular look the same:

• infinitive: odottaa = to wait
• 3rd person singular: odottaa = he/she waits

You tell which one it is from the sentence structure. Since rouva is the subject, odottaa here must be the finite verb: the lady waits / is waiting.

It can mean both.

Finnish does not usually make the same present-tense distinction that English does between:

• waits
• is waiting

So Rouva odottaa toimistossa can mean either:

• The lady waits in the office
• The lady is waiting in the office

The exact meaning depends on context.

Toimistossa means in the office.

The ending -ssa / -ssä is the inessive case, which usually means in or inside something.

Here:

• toimisto = office
• toimistossa = in the office

So instead of using a separate word like English in, Finnish often adds a case ending to the noun.

Because Finnish often uses cases where English uses prepositions.

English says:

• in the office

Finnish says:

• toimistossa

The idea of in is built into the noun ending -ssa. This is very common in Finnish.

Yes, Finnish word order is fairly flexible, although the basic neutral order is:

• Rouva odottaa toimistossa.

You may also see:

• Toimistossa rouva odottaa.

That puts more focus on toimistossa (in the office).
So the word order can change for emphasis, style, or information structure, even though the basic meaning stays similar.

Because the two nouns have different jobs in the sentence.

• rouva is the subject, so it stays in the nominative basic form.
• toimisto expresses location, so it takes the inessive ending -ssa.

So Finnish marks the role of a noun by changing its ending.

Not exactly. Rouva usually means lady, madam, or Mrs. It is more formal and polite than a basic word for woman.

A more general word for woman is:

• nainen = woman

So rouva gives a slightly more respectful or formal tone.

A rough pronunciation guide for an English speaker is:

• rouva ≈ ROU-va
• odottaa ≈ O-doht-taa
• toimistossa ≈ TOI-mis-tos-sa

A few useful points:

• ou in rouva sounds a bit like the vowel in English go followed by a short u glide.
• Double vowels are important: aa is held longer than a.
• Stress in Finnish is usually on the first syllable of each word:
  • ROUva
  • Odottaa
  • TOImistossa

Sometimes yes, depending on context, but the most direct meaning of toimistossa is in the office.

English often uses in and at in ways that overlap. Finnish is usually being more literal here:

• toimistossa = in the office

In natural translation, though, at the office may sometimes sound better in English if the situation calls for it.
