What does "you" mean in informal English

"you" is always the word which is used to refer to the person you are speaking to, whether formal or informal.

Your question is puzzling. Can you explain in more detail what you wish to know?

the topic of it is Pronoun
I guess your answer is probably correct. however i think is it related to subject or object pronoun ?
therefore i guess "you" this word may less use in Informal English whereas it used a lot in formal english.
Maybe "you" is usually used as an object pronoun in informal English
whereas "you" is alway used as subject pronoun in formal English.

Hi Guest,

I encourage you to register. It makes for a more personal experience, though it is not required.

CalifJim's answer is correct, no guessing required.

I think it helps to have some example sentences.

Using GuruNet....

Used to refer to the one or ones being addressed.
I'll lend you the book.
You shouldn't work so hard.

I think you are confusing "you" with some other pronoun.

The English pronoun "you" is unusual in that it is used both as subject and object, both as singular and plural, and both as a formal and an informal pronoun.

Other pronouns have several forms (I, me; he, him; etc.) but "you" is invariable.

thanks all ~~
then i have one more question~
how can i rewirte the following senetences so that they would be acceptable in formal English

1. If you add seventeen and seventy, you get eighty-seven.

2. you have to pay $60 to see a film on Saturdays.

3. You can't be more than five minutes late to this class.

thx

Since you asked about "you", I suppose the point of this exercise is to remove "you" from the sentences. Is that right?

You can substitute the third person "one" for "you", but you can also rephrase the sentences to leave out the "you".

I suggest leaving out the "if ... then" structure in the first one. You can state the mathematical relationship as one simple sentence.
