Language and culture are closely connected in how people communicate and express identity. Language includes spoken, written, and signed systems used by groups of people. Culture includes beliefs, customs, traditions, and ways of life. Together, they shape how people share ideas and understand the world.

Every culture has one or more languages that reflect its history and daily life. Words, expressions, and meanings can be different across regions and communities. Some languages have special terms for local traditions, foods, or environments. Language is used in homes, schools, and public life.

Language and culture develop over time and continue to change. New words and expressions are added as societies grow and interact. People may speak more than one language and belong to more than one cultural group. These connections are found in all societies around the world.
