Old Corellian, also known as Olys Corellisi, represented a venerable language spoken on Corellia. Within the Corellian Spike version of the card game sabacc, the two cards bearing a value of zero were designated sylops, a term that signified "idiots" when translated from Old Corellian. During the era of the New Republic, a musical piece composed in Old Corellian was performed within a lounge situated at Adelphi Base, a New Republic installation located on the planet Adelphi.
