The rules say to only use the words in simplified English in approved ways. This decreases misunderstanding. For example, the rules approve the use of the verb "close" ("Do not close the door"). The rules approve the use of the adjective "closed", meaning "not open" ("The door is not closed"). The adjective "close" means near ("Do not go close to the door"). The rules disapprove the use of the adjective "close". The rules approve the use of the adjective "near" ("Do not go near the door") for this meaning. The rules specify the use of the adjective "near" instead of the adjective "close". This way, the reader can be sure if the instructions say to keep the door open or to stay far from the door.
