Difference between economic and ecomonical 本周末要考了。

What's the difference bewteen the word of economic and the word of economical? Can some niuniu help me? I will take the test this weekend.

economic：是不是“经济的”

economical：是不是“节约的，节俭的”

Thanks so much for your warm heart!

economic - 经济(学)的；

economical - 节约的；

顺便问一声：MM难道身边没有一本字典？CD下载区有longman的可以下载；网上可以登陆m-w.com查阅；再不行，至少搞个kingsoft(金山词霸，注意，只看美国传统字典的解释)什么的；实再再没办法，去bookstore买一本字典也行啊。
