A piknikkosár tele van.

A is the definite article, so it means the.

Hungarian has two forms:

• a before a consonant sound
• az before a vowel sound

Since piknikkosár starts with p, you use a: A piknikkosár.

Because Hungarian commonly writes compound nouns as a single word.

Here it is:

• piknik = picnic
• kosár = basket

So piknikkosár literally combines those into picnic-basket.

One k comes from piknik, and the other comes from kosár.

When Hungarian forms a compound, it usually keeps both letters, so:

• piknik
  • kosár → piknikkosár

So the double kk is normal spelling here.

Tele van is the normal Hungarian way to say is full.

• tele = full
• van = is

So the sentence structure is basically:

• A piknikkosár tele van.
• The picnic basket is full.

This is a very common fixed pattern in Hungarian.

That is a very good question.

In Hungarian, the verb van is often omitted in the present tense, third person singular, especially with simple noun or adjective predicates:

• A ház nagy. = The house is big.
• A fiú diák. = The boy is a student.

But with tele, Hungarian normally uses van:

• A kosár tele van.

So tele van behaves like a set expression. Saying just A piknikkosár tele would sound unusual or incomplete in normal everyday Hungarian.

This is a natural, neutral word order in Hungarian.

It goes:

• topic / subject: A piknikkosár
• description: tele
• verb: van

Hungarian word order is flexible, though. For example:

• Tele van a piknikkosár.

That version puts more emphasis on tele — roughly like The picnic basket is full or It’s full, the picnic basket.

They are very close in meaning, and in many situations both mean full.

A useful rule of thumb is:

• tele van is the very common pattern for is full
• teli is often common before a noun: egy teli kosár = a full basket

So in this sentence, tele van is the standard choice.

Also, do not confuse this with teljes, which usually means complete, entire, or full/whole in a different sense, not full of contents.

Because it is the subject of the sentence, and the Hungarian subject is normally in the nominative form, which has no special ending.

So:

• piknikkosár = picnic basket
• no suffix is needed here

Hungarian often leaves the basic dictionary form unchanged when a noun is the subject.

Hungarian usually uses tele van plus a noun in -val / -vel form.

For example:

• A piknikkosár tele van étellel. = The picnic basket is full of food.
• A piknikkosár tele van szendvicsekkel. = The picnic basket is full of sandwiches.

So the pattern is:

• tele van + something

A simple pronunciation guide is:

• A = short aw
• piknikkosár ≈ PIK-nik-ko-shaar
• tele ≈ TEH-leh
• van ≈ vahn

A few helpful sound notes:

• Hungarian stress is on the first syllable of the word
• s is pronounced like English sh
• á is a long aah sound

So the whole sentence sounds roughly like: aw PIK-nik-ko-shaar TEH-leh vahn
