Hello,<br/>1. <i><b>May</b> I leave the room? <br/></i><br/>2. Can <i> I leave the room?</i><br/>3. Could <i> I leave the room?</i><br/><br/>All these sentences are used for asking the permission. The paraphrase of these three would be the same.<br/><br/>A. Will you permit me to leave the room?<br/><br/>Is #A an equivalent paraphrase of #1,#2 and #3?<br/><br/>Thanks.
