Kilometráž a převýšení jsou důležité.

Because the subject is plural: kilometráž a převýšení = mileage/distance and elevation gain.

• je = is
• jsou = are

Since two things are being talked about together, Czech uses the plural verb:

• Kilometráž je důležitá. = The distance is important.
• Převýšení je důležité. = The elevation gain is important.
• Kilometráž a převýšení jsou důležité. = The distance and elevation gain are important.

It agrees with the subject in number and gender.

Here the subject is a combination of two nouns:

• kilometráž — feminine singular
• převýšení — neuter singular

Together, they form a plural subject. In Czech, when a plural subject is not masculine animate, the adjective usually takes -é in the plural:

• důležité = important (plural, non-masculine-animate)

Compare:

• kilometráž je důležitá — feminine singular
• převýšení je důležité — neuter singular
• kilometráž a převýšení jsou důležité — plural

So důležité is the correct plural form here.

They are in the nominative case because they are the subject of the sentence.

You can identify the subject by asking: What is important?

Answer: Kilometráž a převýšení.

That is why they appear in their basic dictionary forms here.

Because Czech does not have articles like English a/an and the.

So Czech simply says:

• Kilometráž a převýšení jsou důležité.

Depending on context, this could mean:

• Mileage and elevation gain are important
• The mileage and the elevation gain are important

Czech relies on context instead of articles.

In this kind of context, kilometráž usually means the distance in kilometers, or more generally the route length / mileage.

It is often used in contexts like:

• hiking
• cycling
• race routes
• travel descriptions

So it is not just a random number of kilometers; it often refers to the total length of a route or trip.

Převýšení usually means elevation gain or difference in elevation.

In outdoor/sports contexts, it often refers to how much climbing a route includes.

So if a route has a lot of uphill sections, its převýšení is high.

This is a very common word in:

• hiking
• cycling
• mountaineering
• trail descriptions

• kilometráž is feminine
• převýšení is neuter

You can see this from agreement:

• ta kilometráž je důležitá
• to převýšení je důležité

This matters because Czech adjectives and verbs often change depending on the gender and number of the noun.

Yes. Czech word order is fairly flexible.

The neutral order here is:

• Kilometráž a převýšení jsou důležité.

But you could also say:

• Důležité jsou kilometráž a převýšení.

This version puts more emphasis on important.

In English, word order is much more fixed, but in Czech it often changes for emphasis, topic, or style, not basic meaning.

A rough pronunciation guide is:

przhe-VEE-sheh-nee

The hardest part for many learners is ř in pře-.

A few notes:

• pře contains ř, a special Czech sound
• vý has a long ý
• šení sounds roughly like sheh-nee

You do not need perfect ř right away to be understood, but it is worth practicing because it is a very characteristic Czech sound.

Yes. a means and.

So:

• kilometráž a převýšení = distance/mileage and elevation gain

It simply joins the two nouns into one compound subject.

Yes, but the verb and adjective would change to match that one noun.

For example:

• Kilometráž je důležitá.
• Převýšení je důležité.

When both are used together, the sentence becomes plural:

• Kilometráž a převýšení jsou důležité.

So this sentence is a good example of agreement changing depending on the subject.
