[Dutch language] can you help me?

[Migraine]

I'm learning Dutch and I have a few questions:

1. How do you prononce 1 in Dutch? Is it één [e:n] or een [?n]?
What's the difference between both?

2. The book = het boek and the markt = de markt.
So why do you say « de boekwinkel » and « het marktplein »?

3. What's the difference between "is dat/dit", "is die/deze" and "is het/de"?

4. What's the difference between "de boekhandel" and "de boekwinkel"?

[*···¿Qué haces?···*]

i'm dutch so i'll try to help you as much as i can

1. pronounce een like the "ane" in shane

2. thats just the way the grammar is :S

3. die is singular, deze is plural..deze boeken...although you can't say die boek. You would say dit boek...is dat would be proposing a question. anything with is in front proposes a question.

4. they're just 2 different names.

sorry i know the language really well cause i grew up learning it..but i never actually learnt the grammar.
