Core Basic

Core Basic, also commonly known as Trade Basic or Common Basic, was the first most abundant Galactic Basic Standard (particularly Late Modern Basic) dialect in the galaxy. It comprised of several regional accents which were all commonly recurring among different populations. Core Basic's grammar, vocabulary, and structure all directly developed from the Coruscanti, Alderaanian, and Corellian dialects of Early Modern Basic, which were spoken from c. 900 BBY to 400 BBY. During the Imperial era, Core Basic was legally known as Imperial Basic, though this referred specifically to the "upper class accents."

As of 10 BBY, 81.7% of Basic speakers across the Empire's territories identified as speakers of Core Basic according to the Imperial Census Bureau's Linguistic Research Department.

In the Core Worlds, Modern Aurebesh was the standard alphabet, however the Ancient alphabet (also known as Latin) and various phonetic alphabets were nearly as common. Many Human worlds that did not speak Basic as a native language still often had signs with Latin and/or Aurebesh translations for tourists.
