Voisitteko kertoa, mitä vahvuutta haluatte kehittää seuraavaksi?

Voisitteko is built from voida (can / be able to).

Breakdown:

• voi- = verb stem
• -si- = conditional marker
• -tte = you plural / polite you
• -ko = question particle

So voisitteko means could you?

The conditional (-si-) makes the question softer and more polite than voitteko (can you?).

They can be, but not necessarily.

In Finnish, 2nd person plural can mean:

• you all
• or formal/polite you when speaking to one person

So this sentence could be addressed:

• to a group, or
• to one person in a respectful/formal setting

If you wanted a casual singular version, it would be:

• Voisitko kertoa, mitä vahvuutta haluat kehittää seuraavaksi?

Because it sounds more polite and less direct.

Compare:

• Mitä vahvuutta haluatte kehittää seuraavaksi? = direct question
• Voisitteko kertoa, mitä vahvuutta haluatte kehittää seuraavaksi? = softer, more courteous

This is similar to English:

• What strength do you want to develop next?
• Could you tell me what strength you want to develop next?

The longer version is especially natural in interviews, feedback discussions, coaching, HR language, and other formal situations.

Because Finnish often leaves it out when it is obvious from context.

A fuller version would be:

• Voisitteko kertoa minulle, mitä vahvuutta haluatte kehittää seuraavaksi?

But minulle (to me) is not necessary here. The listener already understands who the information is being told to.

This omission is very common in Finnish.

Because the noun phrase is in the partitive.

Here:

• mitä = partitive of mikä
• vahvuutta = partitive of vahvuus

This happens because kehittää often takes a partitive object when the action is seen as an ongoing process rather than a fully completed result. Developing a strength is usually understood as something gradual and open-ended, so the partitive sounds natural.

So:

• mitä vahvuutta haluatte kehittää = what strength would you like to develop

A more definite alternative is possible:

• Minkä vahvuuden haluatte kehittää seuraavaksi?

That version can sound a bit more like choosing one specific strength as a clearly bounded target. The partitive version feels slightly more process-oriented.

Vahvuutta is the partitive singular of vahvuus.

Basic form:

• vahvuus = strength, strong point

Partitive singular:

• vahvuutta

This is a very useful form to learn, because many abstract nouns are often used in the partitive.

Also note that vahvuus in Finnish often means not just physical strength, but also:

• a personal strength
• a skill area
• a strong point

So it fits well in professional or self-development contexts.

Kehittää is the first infinitive of the verb, meaning to develop.

After haluta (to want), Finnish uses the infinitive directly:

• haluan kehittää = I want to develop
• haluatte kehittää = you want to develop

English uses to, but Finnish does not need a separate word there.

As for position, putting the infinitive near the end is very natural in Finnish. The structure is:

• mitä vahvuutta = what strength
• haluatte = you want
• kehittää = to develop

So the clause is built quite naturally according to Finnish patterns.

Seuraavaksi means next or as the next thing.

It comes from seuraava (following / next) plus the ending -ksi, which often gives the sense of into / as / for. In this word, the whole form functions like an adverb.

So seuraavaksi here means something like:

• next
• next up
• as your next development focus

It does not just mean later in a vague way; it suggests the next item in a sequence.

It is an embedded question inside the larger sentence.

Main clause:

• Voisitteko kertoa = could you tell

Embedded question:

• mitä vahvuutta haluatte kehittää seuraavaksi = what strength you want to develop next

So the whole sentence is a polite request that contains a question.

This is similar to English:

• Could you tell me what strength you want to develop next?

Because it is an embedded question, Finnish does not use a word like että here. The question word mitä already introduces the clause.

Yes, it could, but the nuance changes a little.

Compare:

• mitä vahvuutta haluatte kehittää seuraavaksi?
• minkä vahvuuden haluatte kehittää seuraavaksi?

The first one, with the partitive, feels more open and process-based.
The second one, with the genitive/accusative-type object, can sound more definite, like choosing one specific strength as a target.

In real usage, both may appear, but mitä vahvuutta is very natural when talking about self-development as an ongoing process.

A common casual version would be:

• Voisitko kertoa, mitä vahvuutta haluat kehittää seuraavaksi?

Changes:

• voisitteko → voisitko
• haluatte → haluat

That makes the sentence singular and informal, while keeping the same polite could you tell structure.

If you wanted to be even more direct, you could simply ask:

• Mitä vahvuutta haluat kehittää seuraavaksi?

That is perfectly normal too, just less formal.
