A Coruscanti was a person born and raised on Coruscant, or who at least claimed permanent residence on the Galactic Capital. It was also a proper adjective to refer to anything related to, coming from, or similar to that on Coruscant. Obi-Wan Kenobi was said to have a Coruscanti accent, as did some Imperial officers.
The similarly derived term Coruscani saw use in the names of various entities associated with Coruscant, such as the Coruscani ogre and the Coruscani Pilot Institute.
