'Aghlabid' originates from Arabic, specifically the word 'أغلب', where 'Aghlab' was the name of the dynasty's founder, Ibrahim ibn al-Aghlab.

'Aghlabid' changed from the Arabic word 'أغلب' and eventually became the modern English word 'Aghlabid'.

Initially, it referred to the ruling dynasty, and this meaning has largely remained the same in modern usage.
