Cross-border language refers to the different languages spoken by people from different countries or regions that are located close to each other or share a common border.
It’s like when you go on vacation to another country and you hear people speaking a different language than the one you use at home. For example, if you live in the United States and go to visit Mexico, you may hear people speaking Spanish instead of English.
Sometimes, languages can be similar even if they come from different countries or regions. For example, French and Spanish are both Romance languages, which means they have common roots and similar grammar rules. So, if you are a French speaker and you visit Spain, you might be able to understand some of the Spanish language.
Cross-border language can also cause some problems because people may not understand each other due to differences in pronunciation or vocabulary. That's why it’s important to learn new languages and keep communication open between people from different countries and regions. By doing this, we can learn from each other and build stronger relationships.
