Pystytämme teltan ennen pimeää.

It is from pystyttää, which means to set up, erect, pitch. In this sentence, Pystytämme means we set up / we are setting up / we will set up.

The ending -mme shows we. The dictionary form has tt (pystyttää), but in this conjugated form you see only one t: pystytämme.

Finnish usually does not have a separate future tense. The present tense is very often used for future meaning when the context makes it clear.

Here, ennen pimeää (before dark) gives a future time reference, so English naturally translates it as We will pitch the tent before dark.

No. They are different verbs.

• pystyä = to be able to, can
• pystyttää = to set up, erect

They look similar, so learners often mix them up.

For example:

• Pystymme pystyttämään teltan. = We can set up the tent.
• Pystytämme teltan. = We set up / will set up the tent.

Because it is the object of the sentence, and here Finnish uses the total object form.

With a completed action affecting one whole thing, Finnish often uses an object form that looks like the genitive singular:

• teltta = tent
• teltan = the/a tent as a total object

So Pystytämme teltan means that the tent is being put up as a whole, completed action.

Yes, but the meaning would change.

• teltan = the action is seen as complete / whole
• telttaa = partitive object, often used when the action is ongoing, incomplete, or not viewed as a finished result

So:

• Pystytämme teltan. = We will put up the tent.
• Pystytämme telttaa. = We are putting up the tent / We are in the process of putting up the tent

Because ennen (before) takes the partitive case.

So:

• pimeä = dark
• pimeää = partitive form used after ennen

That is why Finnish says ennen pimeää, literally something like before darkness, but naturally in English: before dark.

Yes, pimeä is normally an adjective meaning dark, but here it is used in a more noun-like way.

Finnish often does this. So ennen pimeää means:

• literally: before the dark/darkness
• naturally: before dark

A longer way to say something similar would be ennen kuin tulee pimeä = before it gets dark.

Because the verb ending already tells you the subject.

• -mme = we

So Pystytämme already means we set up / we will set up. Finnish often leaves subject pronouns out when they are not needed.

You can say Me pystytämme teltan ennen pimeää, but the me is optional unless you want emphasis or contrast.

Yes. Finnish word order is fairly flexible, and changing it changes the emphasis more than the basic meaning.

This sentence is natural as:

• Pystytämme teltan ennen pimeää.

But you could also have:

• Me pystytämme teltan ennen pimeää.
• Teltan pystytämme ennen pimeää.

The last version puts more focus on the tent. Finnish uses word order more freely than English.

Because Finnish has no articles.

So teltta / teltan can correspond to a tent or the tent, depending on context.

In this sentence, English might translate it as either:

• We will pitch the tent before dark
• We will pitch a tent before dark

The Finnish sentence itself does not mark that difference with an article.
