I'd like to know the exact meaning of conjunction among <u>as</u>, <u>since</u>, <u>because</u>. <br/><br/>Can 'as' be changed to since or because?<br/><br/>----------------<br/><br/><u>As </u>it was getting dark, we soon turned back.<br/><br/><u>As</u> you are sorry, I'll forgive you.<br/><br/>------------------<br/><br/>I'd appreciate your help. ^^<br/>
