Okay kiddo, do you know what a language is? It's like a way people communicate with each other through words and sounds. Well, African Portuguese is a kind of language that is spoken in some parts of Africa, like Angola and Mozambique.
So you know how there are lots of different types of English, like British English and American English? Well, there are different types of Portuguese too! And African Portuguese is one of them.
But why is it different from regular Portuguese, you might ask? Well, Portugal (a country in Europe) used to have colonies in Africa, and when they went there, they brought their language with them. Over time, the African people started to speak Portuguese too, but they added their own words and accents to it. So African Portuguese has some similarities to regular Portuguese, but also some differences too.
For example, in African Portuguese, they might say "bom dia" instead of "good morning" like they would in regular Portuguese. And they might say some words differently too, like "obrigado" for "thank you".
So that's what African Portuguese is, a language that is spoken in some parts of Africa that has some similarities to regular Portuguese, but also some differences too.
