Listening to my colleagues' rapid-fire Korean, I always pick up on the word 있고. It was used in Beginner S2 #19, but there was no discussion of its use. Google Translate says it means "and", but the translation in the lesson notes suggests it means "have"
근데, 왜 너는 여자친구가 있고, 나는 여자친구가 없어?
Then, why do you have a girlfriend and I don't?
What's the real meaning and when is 있고 typically used?
