Explain the use of sentence-ending particles in Korean and provide examples of their usage.

In Korean, sentence-ending particles are an essential part of the language as they contribute to the overall meaning and tone of a sentence. These particles are attached to the end of a sentence or clause and serve various grammatical functions, such as indicating politeness, making a statement a question, expressing surprise or emphasis, and more. Let's explore the use of some common sentence-ending particles in Korean and provide examples of their usage:

Example: 오늘은 정말 추워요. (Oneureun jeongmal chueoyo.) - Today is really cold.
