We are perfectly aware of the meaning of the definite article.
What we are finding a little difficult is understanding your exact question. Frankly, it really will help both you and us if you use capital letters at the start of sentences, spaces after punctuation, and "I", not "i". Your posts will become much more readable.
The use of articles - whether definite or indefinite - is flexible. There are times when they must be used, usually when something specific is cited:
I went to the shops yesterday
It was a dreadful mistake.
There are times when they are not needed, usually when talking about something in general:
Shops are open all week.
He gets all his information from books.
