dictionary (britannica.com):
one of the meanings of "fund":
a fund - an amount of money that is used for a special purpose
one of examples for this definition:
(1) the library's book fund
To me, (1) is the aggregate of all books in the library.
But according to the definition, (1) has something to do with money rather than books.
Could you please explain to me :
What does (1) mean?
How is (1) related to the dictionary definition?
