The term 'large piece' can be described by two four-letter words: 'HUNK' and 'SLAB'. A HUNK is a large, bulky piece of something, usually referring to food or a physical object. A SLAB is a large, flat piece of material, such as stone, wood, or metal. Both terms are used to describe a large piece of something, but they have slightly different connotations. A HUNK implies a more irregular shape, while a SLAB implies a more uniform shape.
