"What to eat to become pretty?" I think 멀 -> 뭘. ^^

알아[basic form=알다] means "I know/understand" with an informal ending. 그래서 means "So/thus/therefore". I'm not really sure about the last one but I'm guessing it's 이해해요[basic form=이해하다]? This means "Understand/comprehend"

Hi! Learning a language can be tough and it requires a lot of practicing to be good in it :) Firstly, I'd watch Korean dramas and listen to slower Korean songs in order to listen to their pronunciation and then slowly understand what the meanings are. Then, try to understand and read out from a lyrics or a simple article and remember the order of the sentences :D Take it slowly and you'll be fine in no time! Although I'm not advanced in this language but it would be a pleasure if I could do any help.

이따가 스타벅스에 가서 커피를 마시고싶어요. ^^

~(으)러 can only be used with movement verbs like 가다 and 오다, to indicate the purpose of going to a place. -밥을 먹으러 가요. I go in order to eat. -책을 사러 서점에가요. I go to the book store in order to buy a book. #Your sentence "친구를 만나러 왔어." is correct. ~아/어서 means because/therefore. It also functions to connect two closely related events together into a sequence. Not necessary to use it only with 가다/오다. -배가 고파서 밥을 먹어요. I'm hungry, therefore, I eat. *Reason -서점에 가서 책을 사요. I go to the book store and buy a book. *Sequence #Your sentence "친구를 만나서 왔어" is slightly incomplete as it could be:- -여기 와서 친구를 만났어. I came here and met my friend. *Reason/Statement as I do not know whether they met by chance or as planned. -친구를 만나서 같이 우리집에 왔어. I met with my friend and came home together. *Sequence Hope my explanations help~ ^^

-을/-를 is the object marker. It is placed after the object in a sentence. Sometimes, it is omitted but it is better for the object marker to be present. In certain situations, the meaning of a sentence is often being understood even with the absence of the object marker: -공부(를) 해요. Study. -전화(를) 해요. Make a phone call. -빨래(를) 해요. Do the laundry. Other sentences using -을/-를: -밥을 먹어요. Eat rice. -옷을 사요. Buy clothes. -친구를 만나요. Meet a friend. It is also the same for 안/못: -공부(를) 안/못 해요. Doesn't/can't study. -전화(를) 안/못 해요. Doesn't/can't make a phone call. -빨래(를) 안/못 해요. Doesn't/can't do the laundry. -밥을 안/못 먹어요. Doesn't/can't eat rice. -옷을 안/못 사요. Doesn't/can't buy clothes. -친구를 안/못 만나요. Doesn't/can't meet a friend.

"한테" is normally used in spoken language(입말) & "에게" is normally used in written language(글말) "께"는 "한테"와 "에게"의 존댓말이에요. ^^
