I think I really don't know well about the word 'Of'.

  1. The ball flew out of the window.

  2. The ball flew out the window.

Are those sentences the same?

Does the word 'Of' mean a thing like a criteria?

Please let me know the exact concept of the 'Of'.

Thank you so much.

You are asking for something which does not exist: prepositions do not possess "exact concepts" which can be recognized in every particular use. The "meaning" of a preposition depends on context—the particular words it joins—and is determined by historical contingency, not formal analysis of semantic content.

For any preposition it might be possible, with imagination and ingenuity, to work up a core "concept", a single definition which would embrace all the "meanings" the preposition is used to express.

But even if you had such a definition, it would be practically worthless. On the one hand the definition would be so vague that it would not help you understand what "meaning" the preposition was intended to express in any specific context. And on the other hand it would have so much overlap with the meanings of other prepositions that it would not help you predict which preposition you should employ in any given context.

You're not going to learn anything useful by looking for an "exact concept". What you have to learn is the constructions: the meaning expressed by the collocation of a preposition with specific words.

    @JS.Kim., just to add to this answer, when you look up most words in a dictionary, it gives you a meaning of the word. When you look up certain prepositions, especially one like "of", it is described as a "function word", with a long list of functions. They are often less about contributing a specific meaning than acting like grammatical glue that functions to associate certain other words with each other. In your example, "out the window" vs. "out of the window", the "of" just associates "out" with "the window"; the context of "out" is in relation to "the window". – fixer1234 Jun 6 '17 at 21:44
