Irrotamme television sähköverkosta siksi, että valmiustila käyttää sähköä.

Irrotamme is the 1st person plural present tense of irrottaa.

So it means we disconnect, we detach, or in this context very naturally we unplug.

• irrottaa = to detach / disconnect / remove
• irrotamme = we disconnect / we unplug

In this sentence, unplug is the best natural English translation.

Finnish verbs already show the subject through their endings.

Here, the ending -mme in irrotamme tells you the subject is we.

So Finnish often leaves out the pronoun me when it is not needed:

• Irrotamme television... = We unplug the television...

You could say Me irrotamme television..., but that would add emphasis, something like we are the ones who unplug the television.

Because it is the object of the verb, and in this kind of sentence Finnish often uses the genitive singular for a total object.

• basic form: televisio = television / TV
• object form here: television

The idea is that the action affects the whole object as a complete unit:

• Irrotamme television = we unplug the TV / we disconnect the television

This is a very common Finnish pattern:

• affirmative sentence
• singular object
• completed or whole action
  → object often appears in the genitive

So television here does not mean possession. It is an object form.

The ending -sta / -stä is the elative case, which often means out of or from.

Here:

• sähköverkko = electricity network / power network / mains
• sähköverkosta = from the power network / from the mains

The verb irrottaa commonly works with something you disconnect from:

• irrottaa jostakin = to disconnect something from something

So:

• Irrotamme television sähköverkosta
  = We disconnect/unplug the television from the mains

In everyday English, this is usually just we unplug the TV.

Yes. Literally, sähköverkko means electricity network or power grid/network, but in this context it refers to the power supply the TV is connected to.

So the sentence means the TV is being disconnected from electrical power.

Depending on context, Finnish might also use:

• pistorasiasta = from the socket / outlet
• seinästä = from the wall (very common in speech, meaning the wall socket)

But sähköverkosta is perfectly understandable and slightly more formal or technical.

Siksi, että means because.

Literally, it is something like:

• siksi = for that reason / therefore
• että = that

But together, siksi, että functions as a common expression meaning because:

• Irrotamme television sähköverkosta siksi, että valmiustila käyttää sähköä.
• We unplug the television because standby mode uses electricity.

A simpler alternative would be koska:

• Irrotamme television sähköverkosta, koska valmiustila käyttää sähköä.

Both are correct. Koska is often the more direct everyday equivalent of because.

Because että introduces a subordinate clause, and Finnish normally separates subordinate clauses from the main clause with a comma.

So the structure is:

• main clause: Irrotamme television sähköverkosta siksi
• subordinate clause: että valmiustila käyttää sähköä

That is why the comma appears:

• ..., että ...

This is standard Finnish punctuation.

Valmiustila means standby mode or standby state.

It is a compound word:

• valmius = readiness
• tila = state / mode

So valmiustila is the state in which a device is not fully on, but not fully off either.

For example, when a TV looks off but can still be turned on with the remote, it is often in valmiustila.

Because sähköä is in the partitive case, and that is the normal choice here.

• sähkö = electricity
• sähköä = electricity (partitive)

Finnish often uses the partitive for:

• uncountable substances
• something used or consumed in an unspecified amount

Electricity is treated as a substance/resource, so:

• käyttää sähköä = to use electricity / to consume electricity

Using sähkön here would sound unnatural in ordinary Finnish.

Yes, literally it does say that standby mode uses electricity, and that is normal enough in Finnish.

It means that being in standby consumes electricity.

English also does something similar:

• Standby mode uses electricity
• Sleep mode drains the battery

So the sentence is not strange. It is just a compact way to express the idea.

A more explicit version would be:

• Televisio käyttää sähköä valmiustilassa.
• The television uses electricity in standby mode.

Both mean nearly the same thing.

Because irrottaa ... sähköverkosta means disconnect from the power supply, not just turn off.

There is an important difference:

• sammuttaa televisio = turn off the TV
• irrottaa televisio sähköverkosta = unplug the TV / disconnect it from power completely

The sentence is saying that simply leaving the TV in standby is not enough, because standby still uses electricity. So they unplug it entirely.

Yes, absolutely:

• Irrotamme television sähköverkosta, koska valmiustila käyttää sähköä.

This is very natural and probably the version many learners would first meet.

The original version with siksi, että is also correct, but it has a slightly more structured for that reason, because... feel.

So:

• koska = because
• siksi, että = because / for the reason that

In this sentence, both work well.

No, Finnish word order is fairly flexible, although some orders sound more neutral than others.

This sentence has a neutral, clear order:

• Irrotamme television sähköverkosta siksi, että valmiustila käyttää sähköä.

You could also say:

• Irrotamme television sähköverkosta, koska valmiustila käyttää sähköä.

If you change the order, you may change the emphasis rather than the basic meaning.

For learners, the given order is a good standard model:

1. verb
2. object
3. source/place phrase
4. reason clause
