Should I use a or the before every noun that I use? For example, what's the difference between
Late in the winter of my seventeenth year.
Late in winter of my seventeenth year.
The second sentence makes sense to me as the first one.
I can quite understand the use of a before a noun. For example,
I saw book.
doesn't make sense to me and I know I should use a before it to determine which book I mean.
But for example, I don't still know why I should put the before the word use in my above sentence!!:
I can quite understand the use of a before a noun.
Thanks for your help.
