First, Korean has highly developed and detailed particles and verb endings. Each particle and verb ending has a different meaning and grammatical function.
친구가 네 시 비행기로 오기 때문에 공항에 나간다
가 : Subjective, 로 : Adverbial, 기 때문에 : Connecting Adverbial, 다 : Sentence Ending
Second, Korean sentences have the order of a subject, an object, and a verb. While verbs are usually placed at the end of the sentence, other components can be placed freely.
Third, in Korean, honorifics are highly developed. There are various ways for the speaker to express respect for the listener or for the subject of the sentence on many levels. The variety of the levels of expressing respect for others is one of the prominent features of the Korean language.
