Uskon, että hän tulee.

Uskon is the 1st person singular present tense of uskoa, which means to believe.

So:

• uskoa = to believe
• uskon = I believe

Finnish verbs change according to the subject, so the ending -n tells you the subject is I. Because of that, Finnish often leaves out the pronoun minä (I).

So:

• Minä uskon = I believe
• Uskon = I believe

Both are correct, but leaving out minä is very common.

Että means that.

In this sentence, it introduces a subordinate clause:

• Uskon = I believe
• että hän tulee = that he/she is coming / that he/she will come

So the full structure is:

• Uskon, että hän tulee.
• I believe that he/she is coming / will come.

In English, that is often optional:

• I believe that she is coming
• I believe she is coming

In Finnish, että is much more normal and usually should be included in this kind of sentence.

In standard Finnish writing, a comma is normally used before a subordinate clause introduced by että.

So:

• Uskon, että hän tulee.

This is standard punctuation.

English is less strict about this kind of comma, but Finnish uses it regularly in sentences like this.

Hän can mean either he or she.

Finnish does not normally distinguish gender in third-person singular pronouns. So:

• hän = he / she

You understand which one is meant from context.

This is one of the first big differences English speakers notice in Finnish.

In standard Finnish, hän is used for people.

• hän = he/she
• se = it

However, in spoken Finnish, people often use se for humans too. So in casual speech, you may hear:

• Uskon, että se tulee.

But in careful written Finnish, hän is the expected choice for a person.

Tulee is the 3rd person singular present tense of tulla, which means to come.

So:

• tulla = to come
• tulee = he/she comes, is coming, will come

In this sentence, hän tulee can mean:

• he/she is coming
• he/she will come

Which translation sounds best depends on context.

Finnish often uses the present tense to talk about the future when the meaning is clear from context.

So:

• Hän tulee huomenna. = He/She will come tomorrow.
• literally, the verb is present tense, but the time expression makes it future

In Uskon, että hän tulee, the meaning may be understood as:

• I believe that he/she is coming
• or I believe that he/she will come

Finnish usually does not need a separate future tense the way English does.

Yes, grammatically it can.

Tulee is simply present tense, so in theory it can mean:

• he/she comes
• he/she is coming
• he/she will come

But in real use, context decides the most natural interpretation.

In this sentence, after Uskon, että..., English usually prefers:

• I believe that he/she is coming or
• I believe that he/she will come

The simple present he/she comes is usually less natural here in English unless the context is habitual or very specific.

Yes, absolutely.

• Minä uskon, että hän tulee.
• Uskon, että hän tulee.

Both mean the same thing.

Finnish often drops subject pronouns when the verb ending already shows the person. Since uskon already means I believe, minä is not necessary.

Including minä can add emphasis or contrast, for example:

• Minä uskon, että hän tulee, mutta sinä et usko.
• I believe that he/she is coming, but you do not.

Hän is in the nominative, because it is the subject of the clause hän tulee.

A useful thing for English speakers to notice is that Finnish pronouns do not work exactly like English he/she versus him/her. Here, hän is the subject form.

So in:

• että hän tulee
• that he/she comes / is coming / will come

hän is doing the action of coming.

The basic word order here is very standard:

• Uskon, että hän tulee.
• main clause + subordinate clause

Inside the subordinate clause, hän tulee follows the normal subject + verb order.

Finnish word order is more flexible than English, but this sentence uses the most neutral pattern. For a learner, this is the safest version to copy.

Yes. A common alternative is:

• Uskon hänen tulevan.

This also means I believe that he/she is coming / will come.

But this structure is more advanced. It uses a different construction instead of että + a full clause.

For learners, Uskon, että hän tulee is simpler and very natural, so it is usually the better form to learn first.

A few useful pronunciation points:

• ä is not the same as English a
• the double tt is pronounced longer/stronger than a single t
• so että has a clearly long consonant in the middle

Likewise in tulee, the double ee is long:

• tu-lee
• the final ee is held a bit longer than a short e

In Finnish, vowel length and consonant length matter, so double letters are important to pronounce clearly.
