Is "-고" used only for verbs? Or what
Yes, with action or descriptive verbs.
Wasn't there also -서 like 집에가서 참을차요 so why is it 먹고 wouldn't it be 먹서?
서 is more like "and then," while 고 is just regular "and." Because this sentence doesn't imply two consecutive actions, you just use 고.
Can't "I drink and eat" be accepted?
I might be wrong, but bcuz they're putting 먹다 verb first "먹고" and
마시다 verb second "마십니다"...it should follow that order...
Hmm, that has the same meaning but what if someone actually didn't know which word means which
Technically yes but its a matter of the word order. If you say "저는 그녀을 사랑합니다" it would be "I love her" which is different than "she loves me"
But that's not only a change in the word order. You are changing the particles that indicate the subject and object of the action
Technically yes, but its a matter of word order. If you said "저는 그녀를 사랑합니다" it would be "I love her" not "she loves me". That would be a whole new story
Where is "and"? Is it the "고"?
Yep! 고 is a way to connect two verbs in one sentence.
Is "-서" used for vowels and "-고" used for consonant when two verbs are together and "그리고" used for jont two separate sentences?
