Making Polite Sentences
With verb stems which end in vowels such a ka-, ha- and sa- , it is possible to make these into polite sentences by adding -yo to the end of the words, such as Kayo ( which means “to go”, or “I go” or “he goes” ). Verbs in the polite style can be used as statements, questions, suggestions or commands, and may be further emphasized by the tone of your voice. For example, Chal Chinaessoyo may be both expressed as a question by asking how someone is, or can be a question stating that you are fine. Another example is the more common Annyong Haseyo.
