What is the difference between 준비하다 & 마련하다?

How do you use: 맞다, 어울리다? As i know, when i talk about clothes or accessories...v.v * 맞다 = fit ( when i talk about size or standard) eg: 이 옷은 나에게 꼭 맞는다 * 어울리다 = match, suit eg: + 그 셔츠가 네 바지와 잘 어울린다 + 노란색이 너에게 잘 어울린다 The meaning of 맞다 vs 어울리다 are different in this situation. Right? But in this sentence, + 상황에 맞게 행동하는 것이 중요하다 +상황에 어울리지 않게 적극적으로 행동하면 오해를 불러일으키기도 하고 다른 사람에게 피해를 줄 수도 있기때문이다. Can i think that 맞다 vs 어울리다 have the same meaning ? If i use 어울리다 instead of 맞다 in this sentence, Is it right? +안경을 바꾸지 않고 오랫동안 사용하게 되면 안경이 변화된 시력에 맞지 않아 시력을 더 떨어뜨릴 수 있기 때문이다. = 안경을 바꾸지 않고 오랫동안 사용하게 되면 안경이 변화된 시력에 어울리지 않아 시력을 더 떨어뜨릴 수 있기 때문이다. So, when 맞다 vs 어울리다 have the same meaning? Please explain and give for me some examples ! Thank you so much !

How do you use -(으)ㄹ까 싶어? Today, i see this sentence: 그러나 평균 자녀 수가 1.5명도 되지 않는 현실에서 과연 얼마나 많은 가족이 이 행사로 혜택을 볼 수 있었을까 싶다. It is the fisrt time i see this grammar: "-(으)ㄹ까 싶다" After i search in google, i know that it has two meaning. (1) I’m afraid/worried that (this/that would happen…). => -(으)ㄹ까 보다/-(으)ㄹ까 하다/-(으)ㄹ 지도 모르다 has the same meaning with -(으)ㄹ까 싶다? And somebody say that this grammar just use in written/ formal speech. So in communication , what grammar i should use? (2) I (am wondering if I would) want to do this or that… ~ㄹ/을까 싶다 is basically a less determined or certain version of ~고 싶다, right? So if i use -(으)ㄹ까 싶다 in communication for situation that i want to do something but just not very sure yet. Is it right? Please explain it for me ! And give me some examples! P/s: In other hand, If you in two situation above, how do you say? I want to know what Korean really use in communication. Thank you so much !

When do you use 새, 새로,새로이, 새로운, 새롭게? 특히 올해 공연은 신인배우상을 받은 김수영이 새롭게 주인공을 맡아서 꾸미는 무대이기 때문에 더 큰 기대를 모으고 있다. As i understand: this year's performance is highly expected because of Kim Soo-young, who who won the Best New Actress Award, play the lead role in a decorating stage. Is it corect? I don't know how to translate " 새롭게" in this sentence. As i understand " Adjective + 게" work as adverb eg: 깨끗하게 청소했어요 = cleaned clearly 1, And i often see " Adjective + 게" + Verb. So in this sentence " Adjective + 게" + Noun + Verb. " 새롭게 주인공을 맡아서" Does the change position make the meaning change? If i write "주인공을 새롭게 맡아서", how do you understand it? 2, Can i understand the meaning of this sentence that: At this time, Kim Soo-young play the lead role ( In the past, Other person played this lead role, at now has change actor) 3, After met this sentence, i realize that i really don't understand how to use 새, 새로,새로이, 새로운, 새롭게 :(. + If i want to say that: I will buy a new bag ( My bag is old so i think i will buy a new one to replace it) 저는 새 가방을 살 거예요 = 저는 가방을 새로 살 거예요 = 저는 새로운 가방을 살 거예요 (????) But 새롭게 사다 or 새롭게 가다 ..vv: When does you use it? I feel very confused. Please explain it for me and give me some examples !!! Thank you so much !!!

What does 양심 자전거란 이용자가 알아서 이용료를 내는 자전거를 뜻한다 mean? + 문제는 신선도! 알아서 온도를 조절한다. + 양심 자전거란 이용자가 알아서 이용료를 내는 자전거를 뜻한다. I met two sentences in above when i studied. So, i saw " 알아서 N을/를 V" !!!

How i can understand the role of "는" in this sentence? 그런데 모두가 가난하다고 느낄 때보다는 자신이 다른 사람들에 비해 가진 것이 적고, 버는 것이 적다고 느낄 때 더 많이 불행해한다. As i understand this sentence: However, everyone is more unhappy when they feel that they have less and earn less than others than when they feel poor. As i studied: S + (N1)보다 +(N2) + Adj eg: 나는 커피보다 녹차를 좋아한다 I think that in this sentence: => 모두가: is subject => 가난하다고 느낄 때: is N1 => 자신이 다른 사람들에 비해 가진 것이 적고, 버는 것이 적다고 느낄 때: is N2 ????? So i don't understand why use " 는" after "가난하다고 느낄 때보다". Please explain it for me and give me some other examples . Thank you so much ! P.S: And they use "고," after 적(다) when they want to listed something ???? If i say that: 그는 지은 씨가 민지 씨에 비해 예쁘고, 밝다고 느끼다. Is it right?
