"I eat and drink."
Translation:저는 먹고 마십니다.
~고 at the end of 먹고 already means "and" on its own, so 그리고 is unnecessary.
그리고 is the stand alone form. in 머고, the necessary information is already included, as it's attached to the verb stem.
it says in the explanation for this course that 와/과 are only used to link subjects while 고 links verbs :)
Gwa/wa are only used for nouns, I think. When using verbs, use ~go or geurigu
there are so many ways to say "and" in korean I get so confused when its okay to use each of them
