Přístřešek je náš cíl.

The stress is on the first syllable: PŘÍ-stře-šek.

A few useful pronunciation points:

• í is a long vowel, like a longer ee sound.
• š sounds like sh in ship.
• ř is a special Czech sound with no exact English equivalent. It is one of the hardest Czech sounds for learners.
• Czech stress is almost always on the first syllable, so PŘÍ- gets the stress.

A rough learner-friendly approximation is something like PREE-strzhe-shek, but that is only approximate.

Je means is.

It is the 3rd person singular present-tense form of být (to be):

• jsem = I am
• jsi = you are
• je = he/she/it is

So in this sentence, je is simply the linking verb connecting the two nouns.

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

So a noun like přístřešek can mean:

• a shelter
• the shelter

and the exact meaning depends on context.

That is completely normal in Czech.

Because náš has to agree with cíl.

The noun cíl is:

• masculine
• singular
• here in the nominative

So the possessive adjective must also be masculine singular nominative: náš.

Compare:

• náš cíl = our goal
• naše cesta = our journey / our route
• naše město = our city

So náš is the correct form because it matches cíl.

Both are in the nominative.

That is common in simple sentences with být (to be) when one thing is being identified as another:

• To je problém. = That is a problem.
• Praha je hlavní město. = Prague is the capital city.

So in Přístřešek je náš cíl, both noun phrases are nominative.

However, Czech also often allows an instrumental predicate after být, and with a word like cíl, many speakers would also find Přístřešek je naším cílem very natural. So the sentence you have is understandable and grammatical, but Czech may also use the instrumental in similar structures.

Because svůj refers back to the grammatical subject of the sentence.

In this sentence, the subject is přístřešek. So if you used svůj, it would suggest something like the shelter's own goal, which is not the meaning.

You want our goal, so náš is correct.

A useful rule:

• use svůj when the possessor is the same as the subject
• use náš, váš, jeho, její, jejich, etc. when it is not

Yes. Czech word order is more flexible than English word order.

This sentence could be rearranged, but the emphasis would change. For example:

• Přístřešek je náš cíl.
• Náš cíl je přístřešek.
• Naším cílem je přístřešek.

These are all related in meaning, but they do not sound identical in emphasis.

Very roughly:

• putting Přístřešek first can make the shelter the topic
• putting náš cíl or naším cílem first can make our goal the starting point

So the grammar is not only about meaning, but also about information focus.

It is understandable and grammatical, but many Czech speakers might more naturally say:

• Naším cílem je přístřešek.
• Přístřešek je naším cílem.

Using naším cílem is very common in this kind of sentence.

So Přístřešek je náš cíl is fine for learning basic structure, but in everyday Czech, the instrumental version may sound smoother or more idiomatic.

Přístřešek is a masculine inanimate noun.

That matters because Czech nouns belong to grammatical genders, and gender affects:

• adjective forms
• pronouns
• case endings

Here, přístřešek is in the nominative singular, which is the basic dictionary form. Its gender is one of the reasons the rest of the sentence is built the way it is.
