Lisäksi haluan oppia lisää suomea.

Lisäksi means in addition, besides that, or furthermore. It connects this sentence to something said earlier.

In Lisäksi haluan oppia lisää suomea, it signals that this is one more thing the speaker wants:

• Also, I want to learn more Finnish.

It is an adverb, so it does not change form here.

Both are possible, but they place the emphasis slightly differently.

• Lisäksi haluan oppia lisää suomea. = Additionally, I want to learn more Finnish.
• Haluan lisäksi oppia lisää suomea. = I also want to learn more Finnish.

Putting lisäksi first makes it sound more like a sentence connector: it links the sentence to previous information. Finnish word order is fairly flexible, and changing it often changes emphasis rather than basic meaning.

Haluan is the 1st person singular present tense of haluta (to want).

So:

• haluta = to want
• haluan = I want

Some other forms:

• haluat = you want
• hän haluaa = he/she wants
• haluamme = we want

After haluta (to want), Finnish usually uses the first infinitive, which is the basic dictionary form of the verb.

So:

• haluan oppia = I want to learn

Here:

• haluan = I want
• oppia = to learn

This is a very common pattern in Finnish:

• Haluan syödä. = I want to eat.
• Haluan mennä. = I want to go.
• Haluan oppia. = I want to learn.

Yes. Oppia is the first infinitive of the verb oppia, meaning to learn.

It is also the dictionary form. In this sentence it works like English to learn:

• haluan oppia = I want to learn

Yes, lisää means more, and that is exactly what it means here.

In oppia lisää suomea, the phrase means:

• to learn more Finnish

A useful point: lisää often behaves like an amount word. It can modify something that is in the partitive:

• lisää kahvia = more coffee
• lisää aikaa = more time
• lisää suomea = more Finnish

So here lisää is telling us that the speaker wants an additional amount of Finnish learning.

Suomea is the partitive singular of suomi.

This is very common when talking about languages after verbs like oppia (to learn) when you mean learning some of it / more of it / an unbounded amount of it, rather than treating it like a single complete object.

So:

• suomi = Finnish (base form)
• suomea = Finnish (partitive form)

In this sentence:

• oppia lisää suomea = learn more Finnish

The partitive is natural here because:

1. suomi is treated like something you learn in an ongoing, incomplete way
2. lisää often goes with a partitive noun

Yes, but the nuance is a little different.

• oppia lisää suomea = learn more Finnish / learn some more Finnish
• oppia enemmän suomea = learn more Finnish, often with a comparative feeling

Lisää is often the more natural choice when you mean an additional amount.
Enemmän often sounds more explicitly comparative, like more than before or more than something else.

In many everyday situations, lisää suomea is the most natural phrasing here.

Here suomea clearly means the Finnish language.

Finnish uses the same basic word suomi for:

• Finland
• Finnish (the language)

Context tells you which meaning is intended.

Examples:

• Suomi on kaunis maa. = Finland is a beautiful country.
• Opiskelen suomea. = I study Finnish.

In your sentence, because of oppia (to learn), it means the language.

Yes. Both are good translations.

The exact English wording depends on context:

• I also want to learn more Finnish.
• Additionally, I want to learn more Finnish.
• Besides that, I want to learn more Finnish.

Because the meaning has already been given, the main point is that lisäksi adds another idea to what came before.

The written sentence is already natural. In speech, people might still say it exactly like this:

• Lisäksi haluan oppia lisää suomea.

But depending on context, spoken Finnish might also use:

• Mä haluan myös oppia lisää suomea. = I also want to learn more Finnish.
• Lisäksi mä haluan oppia lisää suomea.

Here:

• mä = spoken form of minä (I)
• myös = also

Lisäksi sounds a bit more formal or structured than myös, especially in careful speech or writing.

They can both relate to the idea of also, but they are not used in exactly the same way.

• myös = also, too
• lisäksi = in addition, additionally, besides that

Compare:

• Haluan myös oppia suomea. = I also want to learn Finnish.
• Lisäksi haluan oppia suomea. = Additionally, I want to learn Finnish.

Myös often adds one item directly.
Lisäksi often connects a whole new point to what was said before.

Yes: it is a very common Finnish structure.

It follows this pattern:

verb + lisää + noun in the partitive

Examples:

• lukea lisää kirjaa is not natural, but lukea lisää kirjoja = read more books
• juoda lisää vettä = drink more water
• opiskella lisää suomea = study more Finnish
• oppia lisää suomea = learn more Finnish

So this sentence is a useful model for making similar expressions.

No, suomi would not be correct there.

If you use enemmän or lisää with Finnish as the thing being learned, you still need the partitive:

• enemmän suomea
• lisää suomea

So the correct forms are:

• Lisäksi haluan oppia lisää suomea.
• Lisäksi haluan oppia enemmän suomea.

Not:

• ...lisää suomi
• ...enemmän suomi

Yes, depending on context. Finnish present tense is often broader than English present tense.

• Haluan oppia suomea. = I want to learn Finnish.
• In other contexts, a present-tense verb can cover meanings like learn, am learning, or general ongoing action.

But in this sentence, because of haluan + infinitive, English want to learn is the most natural translation.
