A nő a piacon áll sorban, mert friss zöldséget akar venni.

Both a words are the definite article, meaning the.

• A nő = the woman
• a piacon = at the market

Hungarian has two forms of the definite article:

• a before a consonant
• az before a vowel

So you get a nő, a piac, but az alma.

Because Hungarian usually uses case endings instead of English-style prepositions.

• piac = market
• piacon = at/on the market

The ending -on / -en / -ön is one of the location endings. With piac, the natural form is piacon.

So instead of a separate word like at, Hungarian attaches the location meaning to the noun itself.

It means to stand in line or to queue.

Literally:

• áll = stands
• sorban = in a row / in line

So áll sorban is an idiomatic Hungarian way to say that someone is waiting in a line.

You will also often see the expression as sorban áll. Both are understandable, but word order can affect emphasis.

Because Hungarian word order is much more flexible than English word order, and it often shows emphasis rather than basic grammar.

A more neutral version would often be:

• A nő sorban áll a piacon.

The given sentence:

• A nő a piacon áll sorban...

puts extra attention on a piacon (at the market). It can sound like the location is being highlighted.

So the difference is not mainly about grammar being right or wrong; it is about focus and information structure.

This is the normal Hungarian pattern for want to do something:

• akar = wants
• venni = to buy

So:

• akar venni = wants to buy

This works much like English wants to buy.

Here:

• akar is the finite, conjugated verb
• venni is the infinitive

Because after akar (want), Hungarian normally uses the infinitive.

• venni = to buy
• vesz = he/she buys

So:

• zöldséget akar venni = she wants to buy vegetables

If you used vesz, that would mean an actual finite verb like she buys, not to buy.

Because it is the direct object of venni (to buy), so it takes the accusative ending.

• zöldség = vegetable / vegetables
• zöldséget = vegetable / vegetables as the thing being bought

The accusative ending is basically -t, though in real words it often appears with a linking vowel, as here:

• zöldség → zöldséget

Because in Hungarian, adjectives before a noun usually do not agree with the noun in case or number.

So:

• friss zöldség = fresh vegetable / fresh vegetables
• friss zöldséget = fresh vegetable(s) as object
• friss zöldségek = fresh vegetables

In all of these, friss stays friss.

This is different from languages where adjectives change form to match the noun.

Because Hungarian often uses the singular for food, material, or category words where English prefers a plural.

So:

• friss zöldséget akar venni naturally means she wants to buy fresh vegetables

Even though the Hungarian noun is singular in form, the meaning can be general or collective.

If you say zöldségeket, that sounds more like individual vegetables or different vegetables as separate items.

Because Hungarian distinguishes between indefinite and definite verb conjugation.

Here the object is:

• friss zöldséget

This is indefinite/generic because there is no definite article like a/az, and it does not refer to a specific already-known vegetable set.

So the verb is:

• akar = indefinite form

If the object were definite, you would expect the definite form:

• A nő a friss zöldséget akarja venni.
• The woman wants to buy the fresh vegetables.

Mert means because.

It introduces the reason:

• A nő a piacon áll sorban, mert friss zöldséget akar venni.
• The woman is standing in line at the market because she wants to buy fresh vegetables.

So the first part gives the action, and the mert clause explains the reason.

Because Hungarian normally uses a comma between main clauses and subordinate clauses, including clauses introduced by mert (because).

So the comma here is standard:

• ..., mert ...

This is more regular in Hungarian than in informal English, where comma use before because can vary.

Yes, but the meaning changes:

• A nő = the woman
• Egy nő = a woman

So:

• A nő a piacon áll sorban... refers to a specific woman, or a woman already known from context.
• Egy nő a piacon áll sorban... introduces her as a new, unspecified person.

Both are grammatical; they just mean different things.

A few useful pronunciation notes:

• nő: the ő is a long front rounded vowel, something like a long version of the vowel in German schön or French deux
• piacon: roughly pee-yaw-tson
• zöldséget:
  • zs sounds like the s in measure
  • ö is a front rounded vowel
  • gy is a soft sound, somewhat like the dy in duke for many English speakers
• venni has a doubled nn, so the consonant is held a little longer than in English

Hungarian spelling is very regular, so once you learn the sound values, pronunciation becomes much easier.
