Toto je jediný úsporný spotřebič.

Toto is the neuter form of the demonstrative this.

In Czech, you will often see:

• ten = this / that (masculine)
• ta = this / that (feminine)
• to = this / that (neuter)
• tento / tato / toto = this in a more explicit or formal-sounding way

So:

• to je... = this/that is...
• toto je... = this is... with a slightly more precise or emphatic feel

In everyday speech, to je jediný úsporný spotřebič is often more common than toto je..., but toto je... is perfectly correct.

Je is the 3rd person singular form of být (to be).

Here it matches the subject toto, which functions like this in English:

• toto je = this is

A few forms of být in the present tense:

• jsem = I am
• jsi = you are
• je = he/she/it is
• jsme = we are
• jste = you are / you are (plural)
• jsou = they are

So je is used simply because the sentence is singular: This is ...

Because they are adjectives describing spotřebič, and they must agree with that noun in:

• gender
• number
• case

Spotřebič is:

• masculine
• singular
• here in the nominative

So both adjectives also appear in the masculine singular nominative form:

• jediný
• úsporný
• spotřebič

This is standard Czech adjective agreement.

It is in the nominative singular.

In this kind of sentence with být (to be), Czech normally uses the nominative for the predicate noun:

• Toto je spotřebič.
• To je dům.
• To je učitel.

So in Toto je jediný úsporný spotřebič, the noun phrase jediný úsporný spotřebič is nominative singular.

Not necessarily.

Toto here works as an independent pronoun meaning this. It does not have to agree in gender with the noun that comes after je.

Compare the logic in English:

• This is a machine.
• This is a house.
• This is a man.

English this does not change. Czech does change, but when you use toto as a standalone this, it can introduce something regardless of the gender of the noun that follows.

The noun phrase itself still has its own gender:

• spotřebič is masculine
• therefore jediný and úsporný are masculine

So the sentence is completely normal.

Czech has no articles like English a/an and the.

So a Czech sentence often relies on context, word order, or demonstratives to show whether something is:

• indefinite: an appliance
• definite: the appliance
• specific/deictic: this appliance

Here, English may translate the sentence with the because the meaning of jediný (only) strongly suggests uniqueness:

• the only energy-saving appliance

Czech does not need a separate word for the.

Jediný means only, single, or one and only, depending on context.

In this sentence, it means that among the relevant appliances, this is the only one that is úsporný.

So the structure is:

• jediný spotřebič = the only appliance
• jediný úsporný spotřebič = the only energy-saving appliance

It does not just mean the number one. That would be jeden.

Grammatically, úsporný is an adjective.

Its core idea is saving or efficient in consumption/use. Depending on context, it can mean:

• energy-saving
• economical
• efficient
• low-consumption

With spotřebič (appliance), úsporný usually means something like:

• energy-efficient
• energy-saving

So it describes the appliance as one that uses less energy or resources.

Yes, Czech word order is more flexible than English, but not every version sounds equally natural.

The neutral order here is:

• Toto je jediný úsporný spotřebič.

You could also say:

• Jediný úsporný spotřebič je toto.

But that sounds more marked or emphatic, roughly like:

• The only energy-saving appliance is this one.

So the original sentence is the most straightforward, neutral version.

Yes. That is very common.

Both are correct:

• To je jediný úsporný spotřebič.
• Toto je jediný úsporný spotřebič.

The difference is mostly in style and emphasis:

• to je is more common in everyday speech
• toto je can sound more explicit, careful, or slightly formal

So as a learner, you should definitely recognize both.

Approximately: spo-TRZHE-beech

A more detailed breakdown:

• spo as in spot without the final t
• tře contains ř, a special Czech sound. English does not have it. It is roughly like a rolled or buzzing rzh sound.
• bič sounds like beech, but shorter and crisper

Stress in Czech is almost always on the first syllable, so:

• SPOtřebič

The hardest part for English speakers is usually ř. Even if you cannot say it perfectly at first, a simpler r or zh/r approximation is normal for beginners.

Czech often places multiple adjectives before the noun, just like English:

• jediný úsporný spotřebič

Here:

• jediný = only
• úsporný = energy-saving
• spotřebič = appliance

This order is natural because jediný is more like a limiting adjective, while úsporný is a descriptive one.

If you reverse them:

• úsporný jediný spotřebič

it sounds unnatural or would require a very special context. So in normal usage, the original order is the one you should learn.
