Frequently Asked Question

No. Referees are not usually asked to do this as journals have copy-editors who can correct minor problems with the language. However, if the paper is written so poorly that you cannot clearly understand what the authors mean, or there are so many errors that reading the paper becomes very difficult, then that should be reported back to the journal. Papers whose scientific meaning is unclear, or which have not been properly proof-read by the authors before submission, are usually sent back to the authors for revision.
