Hi
Today in class I said to my teacher " I took your book by wrong"
is that correct ? or should I say " I took your book by a mistake"
Thanx for helping in advance
Hello, Mt,T.
You are using spaces incorrectly. It may seem unimportant: if there is nothing written there, why should we worry about it? But spaces are important. We are used to seeing spaces in certain places and not seeing them in others. When they are placed incorrectly, it distracts us and makes reading more difficult.
The question mark never has a space before it. You should write
Is that correct?
and not
Is that correct ?
Quotation marks always stick to what is inside them. It is incorrect to write
" I took your book by wrong."
You should write
"I took your book by wrong."
(Of course, as 5jj said, the sentence is still incorrect. But even when you are quoting an incorrect sentence, you should use quotation marks and spaces correctly.)
Your punctuation is also incorrect. The problem with your punctuation is that there is too little of it. Remember that every sentence in English must have a punctuation mark at the end. It can be:
or
Also, remember that every English sentence begins with a capital letter.
