That being said, it's possible for an individual from Africa to acquire a pure British accent by living in England. However, it's not guaranteed and several factors can influence how successful they are:
* Age: Children are more likely to acquire native-like accents than adults.
* Length of stay: The longer an individual lives in England and is exposed to the accent, the better their chances of acquiring it.
* Social integration: Interacting with native English speakers regularly and immersing themselves in the culture can significantly help.
* Linguistic background: The individual's native language and accent can influence how easily they can learn a new one.
* Motivation and effort: The individual needs to be motivated and willing to put in the effort to learn and practice.
It's important to remember that accents are complex and involve more than just pronunciation. They also include intonation, rhythm, and other aspects of speech. While some individuals may be able to acquire a very close approximation of a pure British accent, it's highly unlikely they will completely erase their original accent.
Ultimately, acquiring a pure British accent is a challenging but achievable goal for individuals from Africa who are willing to dedicate the time and effort.
