1. '한 해' : it is not different from what you said ealier. But, it only doesn't mean 'new year', you can say "한 해 is over". '한 해' means one year.
2-1. 경건 : em.. This word is also not easy to many koreans :). it comes from classical chinese. It is wrriten in korean, although, its meaning is not korean word exactly. 경건 is a kind of attitude. when you are in a ceremony in memory of sb or praying God for forgiveness, you need to have piety.
2-2. 쭉 : this is very easy :). it can be used like that "you have been studying good, 쭉(=for long time" or "you can make something long from some materials".
쭉 = it basically means 'long' for time, distance, length.
2-3 Why is it written as 늘어나라는 instead of 늘어난다는 의미?
- Not much different from 늘어난다. it is similar with meaning of passive in english.
I think I can give you some examples for your easy understanding.
you can say like
-'I hope my height 늘어나라 like growth of my hair a day.
- I want my money to grow without any efforts(it depends on luck or sb's help)
=> 나는 나의 돈이 늘어나길 바란다.
3. em.. your friend is... korean? I think it's not :p, if so, you don't need to post here :).
it is close more 'to wish, to hope'. you can also use it as meaning of 'to pray'(but, not clear 'to whom', it can be anything, god, the sea, the sky,,)
- I hope that everything is going to be okay.
=> 나는 모든 것이 잘되기를 기원한다.
sorry for my poor english :p
very hard to explain in english hehe.
I hope you understand that I''ve wrriten above.
나는 당신이 좋은 한 해를 보내길 기원합니다..
(= I hope you have a good year ) 한 해 plus 기원
This is the frist time that I've participated here and wrriten for someone.
