I’m going through a referee report (generally positive, yay!) on one of my papers, and I just figured out something about my grammar. When I see the phrase “Let …”, I say in my head “Let , in , …”. My referee apparently says “Let be in …”. As a result, I keep writing sentences like “Let obey ,” which the referee keeps changing to “Let with .” On reflection, I take this pretty far, although I am not perfectly consistent about it. I am much more likely to write “We deduce that lies in ,” than I am to write “We deduce that .”
There’s probably an interesting little linguistics paper waiting to be written on this sort of thing.
