Understanding the Ifa Origin of Yoruba Language
IfaYor aims to advance the understanding of the Ifa origin of Yoruba and human languages, eradicate loan words in Yoruba language and find a suitable replacement for them in or derived from Odu Ifa, develop the Oduduwa-Aebajiogbe, the Yoruba native writing system, for STEM fields, and document the Ifa origin of Yoruba history, proverbs, idioms, and wise sayings.
IfaYor is a living library and a key aspect of CENProject’s Origin of Language (OoL) Project.

The Aebajiogbe STEM Framework
The Aebajiogbe-Oduduwa is an ancient writing system discovered by Oloye Tolúlàṣẹ Ògúntósìn in 2016.
The Oduduwa script is taught to students in Ifẹ (Nigeria), Porto-Novo, Benin, Ifacodemy, among others.


Aebajiogbe STEM develops this great discovery made by Oloye Oguntosin further for application in modern STEM fields and subjects.
It is a key initiative of the IfaYor System, which adapts the ancient Aebajiogbe writing system into a formal framework for teaching and representing modern science, technology, engineering, and mathematics.
