megastore

The word 'megastore' is a modern English compound, a direct and transparent combination of two established elements. The prefix 'mega-', borrowed from Greek, has been a productive component in scientific and commercial terminology since the mid-20th century to signify immense scale, as seen in 'megabyte' or 'megawatt'. It is attached to the word 'store', which has a long history tracing back to the Latin verb instaurare, meaning to renew or establish, evolving through Old French to its current meaning of a retail establishment. The compound thus logically and efficiently creates a term for a retail outlet distinguished not by its type of goods, but by its colossal physical size and extensive inventory, reflecting late 20th-century consumer culture and big-box retail trends.

Structure: mega (large) + store (shop) - mega: From Greek megas (great, large). A combining form used in English to denote something of great size or scale. - store: From Latin instaurare (to set up, restore), via Old French estorer (to build, furnish, supply). In English, it denotes a place where goods are kept for sale.
