Mivel a bolhapiac nagy, több standot megnézünk.

Here mivel means since or because.

So:

• Mivel a bolhapiac nagy... = Since/Because the flea market is big...

Be careful, because mivel can also mean with what in other sentences. For example:

• Mivel írsz? = What are you writing with?

So the meaning depends on context. In your sentence, it is a conjunction introducing a reason.

Because the sentence starts with a subordinate clause:

• Mivel a bolhapiac nagy = reason clause
• több standot megnézünk = main clause

Hungarian uses a comma to separate these clauses, just like English often does with Since the flea market is big, ...

Bolhapiac is a compound noun:

• bolha = flea
• piac = market

So literally it is flea market.

Hungarian forms a lot of compound nouns this way, and they are usually written as one word.

A is the definite article, meaning the.

So:

• a bolhapiac = the flea market

Hungarian has definite and indefinite articles:

• a/az = the
• egy = a/an

Here the speaker is talking about a specific flea market, so a is used.

Because nagy is the predicate adjective: is big.

Hungarian does not use a separate word for is in the present tense when talking about third person singular or plural in sentences like this.

So:

• a bolhapiac nagy = literally the flea market big
• natural English: the flea market is big

This is completely normal Hungarian structure.

In present tense, Hungarian usually omits van (is/are) in third person sentences when describing something.

So:

• A bolhapiac nagy. = The flea market is big.
• not normally A bolhapiac van nagy. ✘

But van does appear in other situations, especially for existence or location:

• A piacon sok stand van. = There are many stalls at the market.

Több can mean more or several, depending on context.

In this sentence, the natural meaning is something like:

• several
• or more than one / multiple

So több standot megnézünk means we’ll look at several stands or we’ll check out more stands.

Because after numbers and quantity words in Hungarian, the noun is usually singular, not plural.

So Hungarian says:

• két stand = two stalls
• sok stand = many stalls
• több stand = several/more stalls

Then if that noun is the direct object, it gets the accusative ending:

• stand → standot

So:

• több standot = several stalls as the object

This is a very important Hungarian pattern: quantity word + singular noun.

Because standot is in the accusative case, which marks the direct object.

The basic noun is:

• stand = stall / booth / stand

As the object of megnézünk, it becomes:

• standot

So:

• megnézünk több standot = we look at/check out several stalls

The accusative ending is often -t, but vowels may be added for pronunciation, which is why you get -ot here.

Stand is a loanword and usually means a stall, booth, or vendor stand, especially in markets, fairs, or exhibitions.

At a flea market, stand refers to an individual seller’s place or table.

The prefix meg- changes the meaning.

• nézünk = we look
• megnézünk = we look at / check out / have a look at

Very often meg- makes the action more complete or goal-directed. In this sentence, megnézünk suggests actually going around and checking the stalls, not just looking in a general sense.

So megnézünk több standot is more natural than just nézünk több standot.

Grammatically, it is present tense, but in context it can refer to the future.

Hungarian often uses the present tense for planned or expected future actions, especially when the context makes the time clear.

So:

• Mivel a bolhapiac nagy, több standot megnézünk.

can naturally mean:

• Since the flea market is big, we’ll look at several stalls.

This is very common in Hungarian.

Because Hungarian verbs have two main conjugations:

• indefinite
• definite

Here the object is több standot, which is not a specific, definite set like the stalls. It is indefinite in meaning, so the verb uses the indefinite conjugation:

• megnézünk

Compare:

• Több standot megnézünk. = We’ll look at several stalls.
• A standokat megnézzük. = We’ll look at the stalls.

So this sentence is a good example of the indefinite conjugation.

Yes, Hungarian word order is quite flexible, but different orders can shift emphasis.

The neutral order here is:

• Mivel a bolhapiac nagy, több standot megnézünk.

This presents the reason first, then the action.

You could also say:

• Több standot megnézünk, mivel a bolhapiac nagy.

That would still be correct, but it feels a bit different in emphasis or flow.

Hungarian word order is influenced a lot by topic and focus, not just by fixed subject-verb-object rules.

Because több already functions as a quantity word, and Hungarian normally does not use an article before this kind of phrase.

So:

• több standot = several stalls
• not a több standot in this meaning

Be careful: a több standot can exist, but then it would mean something more like the other/more stalls in a specific context, not simply several stalls.

Not directly in the same structure.

• mivel usually introduces the reason clause before the main clause:

  • Mivel a bolhapiac nagy, több standot megnézünk.

• mert usually introduces the reason after the main clause:

  • Több standot megnézünk, mert a bolhapiac nagy.

Both can mean because, but they are commonly used in different sentence patterns.

Yes, more or less.

Word by word:

• több = several / more
• standot = stall(s) as object
• megnézünk = we look at / check out

A natural English translation would be:

• we’ll look at several stalls
• we’ll check out several stalls

In theory, the present tense can sometimes be translated as present continuous in English, but in this sentence the most natural interpretation is future-like or habitual planning:

• Since the flea market is big, we’ll look at several stalls.

Without more context, that is the best translation. Hungarian present tense often covers meanings that English separates into present, present continuous, and sometimes future.

The dictionary form is:

• megnéz = to look at, to check out

You can also think of it as:

• néz = to look
• meg + néz = to look at fully / check out

And megnézünk means we look at / we will look at in the indefinite 1st person plural form.
