Sousedé v komunitní zahradě sdílejí nářadí.

• Sousedé = neighbors
• v = in
• komunitní = community
• zahradě = garden (in a form required after v here)
• sdílejí = share
• nářadí = tools / equipment

So grammatically it is literally something like Neighbors in a community garden share tools.

Because v usually requires the locative case when it means in a place.

• basic form: zahrada = garden
• after v for location: v zahradě = in the garden

So:

• komunitní zahrada = community garden
• v komunitní zahradě = in the community garden

This is a very common pattern in Czech:

• v domě = in the house
• ve škole = in the school
• v zahradě = in the garden

Because komunitní belongs to an adjective pattern where several forms look identical.

It still agrees with zahradě in:

• gender: feminine
• number: singular
• case: locative

But with this type of adjective, the ending often remains -í, so the change is not visible.

So even though komunitní looks unchanged, it is still grammatically matching zahradě correctly.

Sdílejí is the 3rd person plural present tense form of sdílet = to share.

The subject is sousedé = neighbors, which is plural, so the verb must also be plural:

• já sdílím = I share
• ty sdílíš = you share
• on/ona sdílí = he/she shares
• oni sdílejí = they share

So Sousedé ... sdílejí ... means The neighbors ... share ...

Sousedé is in the nominative plural because it is the subject of the sentence — the people doing the action.

The neighbors are the ones who are sharing, so Czech uses the nominative for sousedé.

Singular:

• soused = neighbor

Plural:

• sousedé = neighbors

Because nářadí is often used as a collective noun meaning tools / equipment / a set of tools.

It does not behave like a normal countable plural noun in English. In many contexts, Czech treats it more like a mass or collective word.

So:

• sdílejí nářadí = they share tools / they share the equipment

Also, in this sentence nářadí is the direct object, so it is in the accusative, but its form looks the same as the dictionary form.

It is in the accusative case because it is the direct object of sdílejí.

They are sharing what? → nářadí

For this noun, the accusative form looks the same as the basic form, so you do not see a change on the surface.

Yes. Czech word order is more flexible than English because case endings show grammatical roles.

The sentence given is a neutral, natural order:

• Sousedé v komunitní zahradě sdílejí nářadí.

But other orders are possible, for example:

• V komunitní zahradě sousedé sdílejí nářadí.
• Nářadí sdílejí sousedé v komunitní zahradě.

These versions can sound slightly different in emphasis or focus, but the basic meaning stays similar.

Because Czech does not have articles like a and the.

So Czech simply says:

• sousedé = neighbors / the neighbors
• komunitní zahradě = a community garden / the community garden
• nářadí = tools / the tools

Context tells you whether English should use a, the, or no article at all.

A rough English-friendly pronunciation is:

SOU-seh-day f ko-moo-NIT-nee ZA-hra-dye sdee-LAY-ee NAA-rzha-dyee

A few useful pronunciation points:

• ou in Sousedé sounds roughly like oh-oo together
• v is often pronounced like f before a voiceless consonant, so here before k in komunitní, it sounds closer to f
• ě in zahradě makes the d sound softer, roughly like ďe
• ř in nářadí is the famous Czech sound with no exact English equivalent; it is somewhat like a mix of r and zh

Yes, depending on context.

The Czech preposition v literally means in, so:

• v komunitní zahradě = in the community garden

But natural English might sometimes say:

• at the community garden

So the Czech structure is more literally in, even if English sometimes prefers at.

Yes, Czech often omits subjects when they are understood from the verb or context.

• sdílejí already tells you the subject is they
• so V komunitní zahradě sdílejí nářadí can mean In the community garden, they share tools

However, including sousedé makes it clear exactly who they are.

Sousedé is the standard nominative plural form and is very common.

You may also hear sousedi in real usage. Both are used, but sousedé is a very normal standard choice, especially in a textbook-style sentence like this one.
