This is false, and the opposite is true!
A want, used as a noun, refers to something that is not necessary, but something that is wanted, desired only. 
A need, in contrast, refers to something that is necessary, so it is not merely something that is wanted, but something that is very essential.
        
                    
             
        
        
        
Anglo-Saxons liked to gather in the lord's great hall, to eat and drink, and to listen to songs and stories. They loved tales about brave warriors and their adventures. A favourite story told how Beowulf, a heroic prince, kills the fierce man-eating monster Grendel, and Grendel's equally horrid mother. The story of Beowulf was first written down in the 8th-9th centuries, but long before that the story was told around the fire.
