"Variant of Abdullah"
The name Abdullahi is commonly a male name from the "Arabic" origin.
Abdullahi is a form of the Arabic name Abdullah, and it is the usual spelling in Somali and in several other East and West African languages. Abdullah is formed from the Arabic abd, meaning servant, and Allah, so the literal sense is servant of God. The final -i belongs to the spelling conventions of the languages that adopted the name, not to a separate root.
Abdullah means "Servant of Allah.".
The pronunciation of Abdullahi is ab-doo-LAH-hee.
