Is the article presented in an intelligible fashion and written in English?
PLoS ONE staff do not copyedit the text of accepted manuscripts; it is therefore important for the work, as presented, to be intelligible. Perfect, stylish English is not essential but the language must be clear and unambiguous. If the language of a paper is poor, Academic Editors should recommend that authors seek independent editorial help before submission of a revision. A list of scientific editing services can be found in the PLoS ONE Guide to Authors. Poor presentation and language is a justifiable reason for rejection.
