Questions & Answers about 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.
