Politeness levels refer to the varying degrees of formality and respect used in communication, often influenced by social context, relationships, and cultural norms. In many languages, including Japanese and Korean, speakers adjust their language based on the status of the person they are addressing, using different verb forms or vocabulary to convey respect. These levels can be categorized into three main types: formal, informal, and casual. Formal language is used in professional or respectful settings, while informal language is common among friends or peers. Casual language is often used in relaxed environments, reflecting familiarity and comfort between speakers.
