"There are many exercises in this book."

Translation: W tej książce jest dużo ćwiczeń.

As a native speaker I think "w tej ksiazce jest wiele cwiczen" is also a correct answer

[luless]

'Dużo' should really be used with uncountable nouns, 'wiele' with countable. (much, many, respectively) But in everyday language dużo is used with both.

Same goes with ilość and liczba (amount and number).

[Kasia767565]

I disagree. http://sjp.pwn.pl/poradnia/haslo/duzo-i-b-wiele-b;7453.html
it is said that "dużo" and "wiele" can be used in both forms.

Even if... Your comment agrees with me, because "ćwiczenie w książce" is rather countable, they're even numbered.

[JerryMcCarthy99]

Hmmm. "Jest" (not "Są") for "There are <countable objects>"?

[immery]

Polish numerals and quantifiers :

jest+dużo+ genitive

[JerryMcCarthy99]

So "There are many...." would be better thought of, in English, "There is a lot of....". Thanks v. much for the explanation!!

[immery]

Yes. But the rule applies also to most numerals (ones not ending with-dwa, trzy, cztery)

[JerryMcCarthy99]

So "dużo" should be considered to be a number not ending with -dwa, -trzy, -cztery.

[Jellei]

Those that end with -12, -13, -14 also behave just like 'dużo'. Welcome to Polish numerals.

[immery]

Most words that answer "how many/how much" act this way.

When I'm tited, this lesson is a waste, my years of English speaking my way, overrides the lessons. Duzy ogrod, krulik je wzystko.
