Algerian Arabic is a type of language that people in Algeria speak. It is different from the Arabic language that people speak in other countries because it has its own special words and way of speaking.
Just like when you speak with your friends, you have your own words that other people might not understand, like "cool" or "awesome", people in Algeria have some words that are not used in other Arabic-speaking countries.
Sometimes, when people speak Algerian Arabic, they also might use words from French, which is another language that lots of people in Algeria speak.
Even though Algerian Arabic is different from other Arabic languages, people who speak other Arabic languages can still understand some of it because they have similar roots.
In Algeria, most people are bilingual, which means they speak both Algerian Arabic and French. This makes it easier for them to communicate with people from different parts of the world who speak different languages.
So, in short, Algerian Arabic is a special type of language that people in Algeria speak, and it's different from other Arabic languages, but still has some similar words.
