Because of the levelling process toward Sudanese Arabic, Juba Arabic does not allow Time, Mood, and Aspect marking at the same time (note that this is the most important difference between Juba Arabic and Kinubi in terms of degree of creolization). In Juba Arabic, the only possible orders are Tense-Aspect and Tense-Mood (i.e. kan + ge express a continuative action in the past; kan + bi can express both a perfectivity in the future and an anterior-irrealis action).
