I will briefly explain this.... hmmm
Let's compare with English.
Remember - the grammar, especially words' order, is totally opposite! (so if you want to improve Korean fast, you must think like Korean not like English)
Here are examples.
in English,
I(subject)
like(verb)
books (object)
in Korean,
나(I)(subject)
책(books)(object)
좋아한다(like)(verb)
But there are more...
You need to put subject particles after Subject - (
은/는) (이/가)
and you also need to put object particles after Object -
(을/를)
Therefore,
나 책 좋아한다 becomes
나
는 책
을 좋아한다.
so if you want to distingish which part is subject, search for (은/는/이/가)
same to object, in order to find object, search for (을/를)
Remember this as well!
If you say "나 책 좋아한다" in Korea, everyone would understand you perfectly.
even if you say, "나 좋아한다 책" in Korea, everyone would understand you totally.
However, it wouldn't help you improve your Korean skill because further, you would need to say a long sentence in case; for example, "저 어린 아이는 파란색 책을 좋아해"
see, now you get my point.
It's better to say clearly, 나는 책을 좋아합니다. and more importantly, it's very important for you to know exactly what portion of a sentence is Subject/Object/Verb.
There are much more... much more to explain about this grammar.
But, it's better to stop for now. One thing at a time is better than many things at a time!
Practice some simple sentences in Korean. That will help you a lot!!!
cheers,
