In communication, clarification involves offering back to the speaker the essential meaning, as understood by the listener, of what they have just said. Thereby checking that the listener's understanding is correct and resolving any areas of confusion or misunderstanding.
Clarification is important in many situations especially when what is being communicated is difficult in some way. Communication can be 'difficult' for many reasons, perhaps sensitive emotions are being discussed - or you are listening to some complex information or following instructions.
