ibn
The "i" is like the "i" in "bit", the "b" is like the "b" in "bat", and the "n" is like the "n" in "sun".
It's important to remember that the "n" at the end of the word is not pronounced like the "n" in "sing" but rather like the "n" in "bin".
Examples:
* Ibn Battuta (pronounced "ibn bat-too-tuh")
* Ibn Khaldun (pronounced "ibn khal-doon")
* Ibn Rushd (pronounced "ibn rooshd")
It's also worth noting that "Ibn" is an Arabic word meaning "son of". So, for example, "Ibn Battuta" means "son of Battuta".
