There is a rule that when we use the definite article with plural, we imply all the things of that group. I am confused if it can also mean a subgroup of a group.
There are 2 examples:
1) "I love the goods in this shop" - can it mean that I love some of the particular goods among all of them.
2) "I love the books in this library" - the same here, can it mean that I talk about some particular books in the library, not all of them? Or I should have shown it explicitly by mentioning those books with no article in a sentence before this one (like I describe in 3), otherwise it is understood as if I talk about all the books there?
3) As I understand, if I told something like: "In this shop nice tools (mentioning for the first time) are being sold. The tools (2nd mention) are really nice", than it would imply those particular tools but not all of them, correct?
I hope I made my question clear :) Thanks.
