My friend often uses "Couldn't be able to " in almost every sentence<br/><br/>For ex: I couldn't be able to think like that<br/><br/> I couldn't be able to move<br/><br/> I couldn't be able to speak <br/><br/>Though I am not very good at English yet I think it is quite odd to use that way. <br/><br/>I may be wrong. I am not very sure . What is the correct way of saying ?<br/><br/>kindly help me and guide me in this.
