Like: ．Students may use the staff car park. ．Visitors may feed the animals. Are these two OK? Thank you very much for your reply!     Viceidol Joined on Wed, Jul 11 2007 Taiwan Regular Member 540

Students may wish to use the restroom before boarding the bus.  (Ouch! this is a different sense of "may."  Guess I'm having a bad day.) Students may refer to their textbooks during the exam.

	CalifJim  +  485479 Thu, 06 Mar 08 03:40 AM In these sentences, may and may not are essentially opposites.  Whenever you have this sense of may (have permission to), may not (do not have permission to) is also possible . You may park here.  =  You have permission to park here. You may not park here.  =  You do not have permission to park here. may grants permission; may not denies it.
