In English, there is only one way to say “And”, but in Korean there are a few of them.

Today you will learn connecting words which are 와/과, 하고, and (이)랑.  You can use the 와 after a vowel ending and use 과 after a consonant ending, ex: I ate peaches and apples/ 나는 복숭아와 사과를 먹었어요, I ate water melons and orange/ 나는 수박과 오랜지를 먹었어요. Please see the video below for pronunciation. In the video, 와/과 and 하고 is little different, but not really different. I usually explain to my student that 와/과 first and most of my students are confused because of unique grammar rule. So, I just tell my student to use 하고 instead of 와/과 because you can use 하고 after the ending vowel and consonant. For instance, (나는) 복숭아하고 사과를 먹었어요 and (나는) 수박하고 오랜지를 먹었어요 are totally fine to say and are the same meaning of using 와/과.  The reason why explaining 와/과 is for my students’ listening skill. (이)랑 is kind of different; it is casual, so many Korean use (이)랑. 랑 is after a vowel ending and 이랑 is after a consonant ending. Ex, I ate lunch with Cheol Soo/(나는) 철수랑 밥먹었어요. I went to beach with Bob/ (나는) 밥이랑 바닷가에 갔어요. Leave a comment below if you have any question.
