Roskis on täynnä, joten vien roskapussin ulos.

Roskis means trash can / bin.

It is a very common informal word in Finnish. In more formal language, you might also see words like:

• roskakori = wastebasket / trash bin
• jäteastia = waste container

So in everyday speech, roskis is completely normal.

Finnish does not have articles like the or a/an.

So:

• roskis can mean the trash can, a trash can, or just trash can
• the exact meaning comes from context

In this sentence, the context makes it clear that it means the trash can.

Finnish often leaves out subject pronouns when they are not needed, and it also often uses the noun directly instead of repeating a pronoun.

So Roskis on täynnä is simply:

• The trash can is full

You could say Se on täynnä if the bin had already been mentioned and you wanted to say It is full, but here naming the bin directly is more natural.

Täynnä means full.

In the sentence:

• Roskis on täynnä = The bin is full

This is a very common expression in Finnish:

• olla täynnä = to be full

Often Finnish can also say what something is full of:

• Lasi on vettä täynnä = The glass is full of water

But in your sentence, that extra part is not needed, because the meaning is obvious.

Joten means so, therefore, or therefore/as a result.

It links the two ideas:

• Roskis on täynnä = The bin is full
• joten vien roskapussin ulos = so I’ll take the trash bag out

It sounds a bit like a logical consequence: because this is true, that follows.

In everyday speech, people may also use other connectors such as:

• niin = so
• siksi = therefore / that’s why

But joten is very common and natural.

Vien comes from the verb viedä, which means to take / carry / bring away.

Here is the present tense:

• minä vien = I take
• sinä viet = you take
• hän vie = he/she takes
• me viemme = we take
• te viette = you (plural) take
• he vievät = they take

So:

• vien roskapussin ulos = I take the trash bag out

Notice that Finnish usually drops minä when it is obvious from the verb ending, so vien by itself already means I take.

Because it is the object of the verb, and here it is a total object.

• roskapussi = trash bag
• roskapussin = the trash bag (as a completed object)

In vien roskapussin ulos, the idea is that the whole bag is being taken out, as a complete action. That is why Finnish uses the total object form.

For singular nouns, the total object often looks like the genitive form:

• roskapussi → roskapussin

Compare:

• Luen kirjan. = I read the book / I will read the whole book.
• Luen kirjaa. = I am reading a book / I’m reading the book, but the action is incomplete or ongoing.

So roskapussin suggests taking out the entire bag.

Ulos means out or outside, with a sense of movement toward the outside.

That is important: Finnish often distinguishes between:

• outside as a place
• going to the outside

Here, there is movement, so ulos is correct:

• vien roskapussin ulos = I take the trash bag out/outside

Compare:

• ulkona = outside, being outside
• ulos = out, to the outside

So:

• Olen ulkona. = I am outside.
• Menen ulos. = I go outside.

Finnish very often uses the present tense for actions that are about to happen or are intended next.

So:

• vien roskapussin ulos

can mean:

• I take the trash bag out
• I’m taking the trash bag out
• I’ll take the trash bag out

The exact time sense comes from context. In this sentence, it naturally sounds like an immediate future action: the bin is full, so I’ll take the bag out.

Because the verb ending already tells you who the subject is.

• vien = I take

Finnish usually omits personal pronouns when they are not needed for clarity.

So both are possible:

• Vien roskapussin ulos.
• Minä vien roskapussin ulos.

The version without minä is more neutral and common. Adding minä can give emphasis, as if saying I will do it.

Yes. Finnish uses compound words very often.

• roska = trash, garbage
• pussi = bag
• roskapussi = trash bag

Then in the sentence it becomes roskapussin because of the object form.

Similarly:

• roskis is related to roska
• many Finnish everyday words are compounds like this

Learning to spot the parts of a compound word can make vocabulary much easier.

That is a very natural word order in Finnish.

• Vien roskapussin ulos sounds normal and neutral.

Finnish word order is somewhat flexible, but not random. The most neutral order here is:

• verb + object + direction

You may also hear other orders for emphasis, for example:

• Roskapussin vien ulos. = It’s the trash bag that I’m taking out.
• Ulos vien roskapussin. = marked/emphatic, less neutral

So the original sentence has the most everyday, unmarked order.

Because joten connects two clauses, and Finnish normally separates them with a comma.

Here the clauses are:

• Roskis on täynnä
• joten vien roskapussin ulos

So the comma is standard punctuation.

A native speaker expects that comma there.
