I'm a native Korean speaker but I also sometimes mess up my Korean. My solution to such an issue is that I break down what I want to say and speak multiple short sentences usually ending with "요". And I use conjunctions such as "그런데(but)", "그래서(so)", "그리고(and) etc to connect the sentences. 1) 가능하면 도시 시내에서 살고 싶고 제 아파트의 가구를 다 직접 고르면 좋겠어요. I suppose that you may want to say "I want to live in downtown in a city if possible. And I, myself, want to pick my furniture for my apartment." I would say, "가능하면 도시 (시내)에서 살고 싶어요. 그리고 (제 아파트의) 가구는 제가 직접 고르고 싶어요." 2) 사실은 아주 큰 데는 필요 없고 그냥 나만 살 수 있는 데가 있으면 돼요. I think that you may want to say "Actually, It doent's have to be so big. I just want a properly-sized apartment for a single." I would say "(사실) 아주 클 필요는 없구요. 혼자 살 정도의 크기면 돼요." 3) 물론 다른 친구들과 함께 사는 것이 괜찮은데 삼년 동안 기숙사에 사는 후에 아마 <좀 쉬고(?)> 싶을 거예요. (좀 쉬고) => do mean by "rest"? "쉬다" means "to rest" or "to have a break." I guess that you may want to say "It's okay to live with friends, but I may want to live on my own after three years in the dorm." I would say, "(물론) 친구들과 사는 것도 괜찮아요. 그래도 기숙사에서 3년 살고 나면 혼자 살고 싶을 거에요." Great job on your Korean! I understand exactly what you are trying to convey.

Basically, "또" and "다시" are the same, meaning "again". You may have come across "또다시". In this case, "또" is just used to emphasize "다시" in Korean. It would be translated with "once again" or "once more" in English. ex) 그는 <또다시> 실패했지만 실망하지 않았다. (He failed <once more>, but he wasn't disappointed.) <또다시> 이와 같은 일이 일어나지 않도록 하세요. (Make sure that such a thing will not happen <once again>.) --------------------------------------------------------------------------------------------------------- And I wanna tell you another meaning of "또". In this usage, there can be many sentences. But the overall meaning is that you "add something else to something". ex) 무엇이 <또> 필요하세요? (What <else> do you need?) 그 케이크 맛있던데 <또> 남은 거 없어? (I really liked the cake, do you have <any other> cake left over?) 내가 거기에 있었을 때 <또> 이런 일도 있었다. (When I was there, this event <also> happened.> 그거 말고도 <또> 중요한 것은 그 사진이다. (Besides this, what's <also> important is the photo.> ------------------------------------------------------------------------------------------------------------------------------- Explaining the concept of "딱" is not easy, but let me give it a shot by example sentences. 1) exactly 그거 딱 좋아! (That's exactly what I like.) 그 옷들은 나한테 딱 맞아! Those clothes exactly fit me. (So, they are probably too tight on you.) 2) just or only <Imagine that you haven't yet finished your homework and the due date is only 30 minutes away. Then you could beg your teacher to have mercy on you and give you more time to complete it> <딱> 한 시간만 더 주세요. (Please! Give me <just> one more hour!) 3) It is used to stress the very moment when something happens. 내가 몸을 돌리자 <딱> 그 사람과 눈이 마주쳤다. (As I turned around, <it was at that moment that> I met the person's eyes.>

특기 means what you are the best at or your special talent or ability. 특징 is what makes you unique or special from other people. 특성 could be translated with "attribute" or "feature". Hope it helps you.
