Student or Learner
I would like to know if you have a grammar rule relating to only if, because in my language we would say : ONLY IF A TEACHER HAS GIVEN PERMISSION THE STUDENT IS ALLOWED TO LEAVE and ONLY IF THE RED LIGHT COMES ON THERE IS ANY DANGER TO EMPLOYEES, and in english it seems to be the opposite order. Can I always invert the order???
Only if a teacher has given permission is a student allowed to leave the room.
Only if the red light comes on is there any danger to employees.
