| | to run out vs to run out of something
I would like to make up four sentences.
(1) I ran out of these pamphlets.
(2) These pamphlets ran out.
(3) This particular pamphlet ran out.
(4) This particular pamphlet ran out of copies.
I do not have any questions about (1) and (2). If you compare (3) and (4), (4) has two extra words at the end, which are "of copies".
Is it grammatically wrong to add the two words there? Thank you for your help.
