And
From Jonathan Gardner's Korean Notebook
There are many ways to say "and" in Korean. All of them are slightly different.
Noun and Noun
When you want to group nouns together (this and that), then you need to use a noun connector.
Verb and Verb
When you want to group verbs together (sit and eat), you need one of the 연결 어미 (Connective Ending).
부사 (Adverb)
Of course, Korean supports adverbial "and" as well, which is what you use when you want to connect entire ideas.
