Levantine Arabic is a way people talk in a certain part of the world called the Levant. The Levant is made up of countries like Syria, Lebanon, Jordan, and Palestine. Levantine Arabic is not one language because each country speaks a slightly different version of it. It's like when you and your friends have different accents even though you all speak the same language.
Levantine Arabic has some words that might be different from what you know if you only speak English. For example, if you want to say thank you in Levantine Arabic, you would say "Shukran" instead of "Thank you." It's like learning another way to say something, just like how sometimes you might say "pop" instead of "soda."
In Levantine Arabic, people might also talk a little differently than you're used to. They might make longer sounds with some of their words, like when they say "Sa'af" instead of "Saif" for the word "summer." Or sometimes they might say the "q" sound instead of the "k" sound, like when they say "qamar" instead of "kamar" for the word "moon."
Overall, Levantine Arabic is just a way that people in some countries talk, and it's a little different from English. But just like how you can learn different words and ways of talking from your friends, you can learn Levantine Arabic if you want!
