Klub má společnou místnost.

• Klub = club
• má = has
• společnou = common, shared, or communal (depending on context)
• místnost = room

So the sentence literally reads: Club has shared room, which in natural English is The club has a shared/common room.

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

So Klub can mean the club or a club, depending on context, and místnost can mean a room or the room if the situation makes it clear.

That means:

• Klub má společnou místnost could be translated as The club has a shared room or A club has a shared room.
• In most contexts, the club is the most natural translation.

Má is the 3rd person singular form of the verb mít, which means to have.

Forms of mít include:

• mám = I have
• máš = you have
• má = he/she/it has

Since klub is singular, you use má:

• Klub má... = The club has...

Because společnou is an adjective describing místnost, and Czech adjectives must agree with the noun in:

• gender
• number
• case

Here, místnost is:

• feminine
• singular
• accusative (because it is the direct object of má)

The feminine singular accusative ending of this adjective is -ou, so:

• společná místnost = a shared room (nominative)
• má společnou místnost = has a shared room (accusative)

Místnost is in the accusative case.

Why? Because it is the direct object of the verb má:

• the club has what?
• společnou místnost

In Czech, the thing directly affected by a verb like mít is usually in the accusative.

That is a very common thing to notice.

Místnost is a feminine noun, but it belongs to a declension pattern where the nominative singular and accusative singular are the same.

So:

• nominative: místnost
• accusative: místnost

But the adjective does change:

• nominative: společná
• accusative: společnou

So the case is shown more clearly by the adjective than by the noun itself.

Klub is masculine inanimate.

Yes, that matters for agreement in other contexts, but in this sentence it mainly matters because it is the subject of the verb:

• Klub má...

The verb form má works for any singular third-person subject, so you do not see a special masculine ending on the verb here.

It is a very natural way, but not the only one.

Depending on context, společnou místnost can mean:

• a shared room
• a common room
• a communal room

Other adjectives might be used in different situations, but společnou místnost is a normal and correct phrase.

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

The neutral order here is:

• Klub má společnou místnost.

But other orders are possible, for example:

• Společnou místnost má klub.
• Má klub společnou místnost? = Does the club have a shared room?

Changing the word order often changes the focus or emphasis, not the basic meaning.

Because it is the subject, and this is the most neutral, straightforward word order in Czech:

• subject + verb + object

So:

• Klub = subject
• má = verb
• společnou místnost = object

This is the most natural order if you are simply stating a fact.

A few useful pronunciation points:

• í in místnost is a long vowel.
• společnou contains č, which sounds like ch in church.
• ou in Czech is usually pronounced like the ou in go
  • oo blended together, as one diphthong.

Roughly:

• místnost ≈ meest-nost
• společnou ≈ spo-lech-noh

Not exact English spellings, but close enough to help.

You would say:

Klub má společné místnosti.

Changes:

• místnost → místnosti (plural)
• společnou → společné (to agree with the plural noun)

So:

• Klub má společnou místnost. = The club has a shared room.
• Klub má společné místnosti. = The club has shared rooms.

Yes, but the structure and emphasis are different.

• Klub má společnou místnost. = The club has a shared room.
  • Focuses on possession / having
• V klubu je společná místnost. = There is a shared room in the club.
  • Focuses on existence / location

Both can be correct, but they are not exactly the same sentence.
