Musíme snížit spotřebu energie.

Musíme means we must or we have to.

It is the 1st person plural form of the verb muset (to have to / must).

• musím = I must
• musíš = you must
• musí = he/she/it must
• musíme = we must
• musíte = you must (plural/formal)
• musí = they must

In this sentence, the subject we is already included in musíme, so Czech does not need a separate my.

Because Czech verb endings usually show the subject clearly.

Musíme already tells you the subject is we, so my would normally be unnecessary.

• Musíme snížit spotřebu energie. = We must reduce energy consumption.
• My musíme snížit spotřebu energie. = also possible, but my adds emphasis, like we really must...

This is very common in Czech: subject pronouns are often omitted unless they are needed for emphasis or contrast.

Snížit means to reduce, to lower, or to decrease.

It is in the infinitive because it follows musíme. After modal verbs such as muset (must), Czech usually uses an infinitive:

• Musíme jít. = We must go.
• Musí pracovat. = He/she must work.
• Musíme snížit spotřebu energie. = We must reduce energy consumption.

So the structure is:

musíme + infinitive

This is about aspect, which is very important in Czech verbs.

• snížit = perfective
• snižovat = imperfective

Here, snížit is used because it refers to achieving a result: bringing consumption down.

So:

• Musíme snížit spotřebu energie. = We must reduce energy consumption.
  Focus: the reduction should be accomplished.

By contrast:

• Musíme snižovat spotřebu energie. = We must be reducing / keep reducing energy consumption.
  Focus: the ongoing process or repeated effort.

English often uses just reduce for both ideas, but Czech makes this distinction more clearly.

Because spotřeba is the direct object of the verb snížit, so it must be in the accusative case.

The dictionary form is:

• spotřeba = consumption

But in the accusative singular, it becomes:

• spotřebu

This is a common pattern for many feminine nouns ending in -a:

• kniha → knihu
• cena → cenu
• spotřeba → spotřebu

So:

• spotřeba = nominative, the basic form
• spotřebu = accusative, used here because it is what is being reduced

Because energie is not the main direct object. It depends on spotřeba and means of energy.

So the phrase is:

• spotřeba energie = consumption of energy

Here, energie is in the genitive singular, which is often used in Czech to express of relationships.

The whole object is:

• spotřebu energie = energy consumption

Within that phrase:

• spotřebu is accusative because it is the direct object of snížit
• energie stays genitive because it depends on spotřeba

Yes. That is the literal structure.

• spotřeba = consumption
• energie = of energy

So Czech expresses this idea a bit differently from everyday English, where energy consumption sounds more natural than consumption of energy.

This kind of noun + genitive structure is very common in Czech:

• cena domu = the price of the house
• výroba elektřiny = production of electricity
• spotřeba energie = consumption of energy

The neutral word order is:

Musíme snížit spotřebu energie.

This is a natural, standard way to say it.

Czech word order is more flexible than English because case endings show grammatical roles. So other orders are possible, especially for emphasis:

• Spotřebu energie musíme snížit.
  Emphasizes energy consumption.

• Snížit spotřebu energie musíme.
  More marked; emphasizes the necessity.

But for a learner, the given order is the safest and most neutral.

A rough pronunciation guide is:

MOO-shee-meh SNEE-zheet SPOH-treh-boo EH-nehr-gee-eh

A few key points:

• š sounds like sh in shoe
• ž sounds like the s in measure
• ř is a special Czech sound; in spotřebu it is the famous Czech ř, which can be difficult for learners
• í is a long ee
• stress in Czech is usually on the first syllable of each word:
  • MU-síme
  • SNÍ-žit
  • SPOT-řebu
  • E-nergie

If ř is hard, that is completely normal for English speakers.

The accent marks mainly show vowel length.

• í is a long vowel, pronounced longer than i
• So:
  • musíme has a long í
  • snížit also has a long í

In Czech, vowel length can change meaning, so it is important to notice it.

The letter ž in snížit is not about length; it is a different consonant sound, pronounced like the s in measure.

Czech has no articles, so there is no direct equivalent of a/an/the.

That is why Czech simply says:

Musíme snížit spotřebu energie.

Depending on context, English might translate this as:

• We must reduce energy consumption.
• We must reduce the consumption of energy.
• We must reduce our energy consumption.

Czech leaves that kind of definiteness to context instead of using articles.

Yes, in many contexts that would be a natural English translation.

Musíme is often translated as:

• we must
• we have to
• we need to

The exact English choice depends on tone:

• must = stronger, more direct
• have to = very common and neutral
• need to = often slightly softer in English

But in Czech, musíme itself is straightforward and commonly used.

The pattern is:

Musíme + snížit + spotřebu energie

Or in grammar terms:

modal verb + infinitive + direct object

More specifically:

• Musíme = finite verb, we must
• snížit = infinitive, to reduce
• spotřebu energie = object, energy consumption

So the sentence is built very economically:

We must reduce energy consumption.
