A közös tér zsúfolt.

• a = the
• közös = shared / common
• tér = space / area / hall / square, depending on context
• zsúfolt = crowded / packed

Grammatically:

• A közös tér is the subject: the shared/common space
• zsúfolt is the predicate adjective: crowded

So the structure is basically The shared space is crowded.

In Hungarian, in the present tense, third person singular, the verb to be is usually left out when the sentence is simple and descriptive.

So English:

• The shared space is crowded.

Hungarian:

• A közös tér zsúfolt.

This is completely normal.

You do use forms of to be in other persons, for example:

• Zsúfolt vagyok. = I am crowded (not very natural in meaning, but grammatically it shows vagyok = am)
• Zsúfoltak vagyunk. = We are crowded

And in past or future tenses, the verb appears:

• A közös tér zsúfolt volt. = The shared space was crowded.

No. Hungarian a here means the, not English a/an.

Hungarian has two definite articles:

• a
• az

Which one you use depends on the following sound:

• a tér because tér begins with a consonant
• az iskola because iskola begins with a vowel

So:

• a közös tér = the shared space

If you wanted an indefinite meaning, you would use egy:

• Egy közös tér zsúfolt. = A shared space is crowded.

Hungarian adjectives do not agree with nouns in gender, because Hungarian has no grammatical gender.

So közös stays közös whether the noun would be masculine, feminine, or neuter in other languages.

In a basic attributive position like this, the adjective also does not change for singular:

• a közös tér = the shared space

But in some predicate plural sentences, the adjective can take a plural ending:

• A közös terek zsúfoltak. = The shared spaces are crowded.

So Hungarian is much simpler than many Indo-European languages in this respect.

Közös usually means shared, common, or communal.

Depending on context, a közös tér could mean:

• a shared room
• a common area
• a communal space
• a common hall
• a shared public area

So közös suggests that the space is used by more than one person or group.

Yes, tér can mean different things depending on context.

Common meanings include:

• space
• area
• square (as in a town square)
• sometimes a named public place, like Hősök tere = Heroes’ Square

In A közös tér zsúfolt, the most natural interpretation is something like:

• the common area is crowded
• the shared space is crowded

So here tér is probably space/area, not necessarily an outdoor city square.

A rough guide:

• közös ≈ KUH-zhush
• tér ≈ tayr
• zsúfolt ≈ ZHOO-folt

A few important sounds:

• zs sounds like the s in measure
• ö is a rounded vowel that English does not really have; it is similar to German ö
• é is a long vowel, roughly like ay in say, but pure and steady
• ú is a long oo
• cs, sz, zs, gy, ny, ty are all fixed Hungarian letter combinations, so it helps to learn them early

Also, Hungarian stress usually falls on the first syllable of each word:

• KÖ-zös
• TÉR
• ZSÚ-folt

Zsúfolt usually means crowded, packed, or overfilled with people or things.

It often suggests:

• not much room
• too many people
• a busy, cramped feeling

So it is stronger and more specific than just full.

Compare:

• A terem tele van. = The hall is full.
• A terem zsúfolt. = The hall is crowded / packed.

A place can be full without feeling especially crowded, but zsúfolt usually gives the sense of crowding.

Yes. Hungarian word order is flexible, and changes in word order often affect focus or emphasis rather than basic grammar.

Neutral statement:

• A közös tér zsúfolt. = The shared space is crowded.

If you say:

• Zsúfolt a közös tér.

that can sound like you are putting more focus on crowded:
The shared space is crowded / It’s the shared space that is crowded / Crowded is what the shared space is.

For a learner, A közös tér zsúfolt. is a very safe, neutral pattern.

Normally, no. That sounds unnatural in standard Hungarian.

Hungarian often uses articles where English might not, and in a sentence like this, you would usually want:

• A közös tér zsúfolt.

Without the article, it sounds incomplete or unnatural unless you are speaking in a very special style, such as notes, headlines, or labels.

This is the basic dictionary form of the words.

• a közös tér is in the nominative as the subject
• zsúfolt is a predicate adjective, also in its basic form

There are no visible case endings here because nothing is being marked as in, to, from, with, and so on.

If you changed the role of tér, you would add a case ending:

• a közös térben = in the shared space
• a közös térre = onto the shared space
• a közös térről = from the shared space

You would make the noun plural, and the predicate adjective usually becomes plural too:

• A közös terek zsúfoltak. = The shared spaces are crowded.

Changes:

• tér → terek = spaces
• zsúfolt → zsúfoltak = crowded for a plural subject

This is a useful pattern:

• singular: A szoba nagy. = The room is big.
• plural: A szobák nagyok. = The rooms are big.

Not by itself. Tele van usually needs something after it, because it means is full of ...

For example:

• A közös tér tele van emberekkel. = The shared space is full of people.
• A közös tér tele van bútorral. = The shared space is full of furniture.

By contrast, zsúfolt can stand alone:

• A közös tér zsúfolt.

So:

• zsúfolt = a complete description by itself
• tele van = usually needs a complement

Yes, it is natural and grammatically correct.

A native speaker might also choose a more specific noun depending on the situation:

• A közös helyiség zsúfolt. = The common room is crowded.
• A közös tér nagyon zsúfolt. = The common area is very crowded.
• Zsúfolt a közös tér. = same meaning, with different emphasis

But A közös tér zsúfolt. is perfectly good Hungarian.
