Shopping malls are large, multi-level complexes that typically contain a variety of stores and services. The two most common terms used to describe them are 'GALLERIA' and 'PLAZA'. GALLERIA is an 8-letter word that comes from the Italian word for gallery, and it is often used to refer to a shopping mall with a more upscale atmosphere. PLAZA is a 5-letter word that comes from the Spanish word for public square, and it is often used to refer to a shopping mall with a more casual atmosphere. Both terms are used interchangeably to refer to a shopping mall.
