Translation:The ocean is wide.
Rules for consonant pairs:
If the next syllable block starts with a vowel, pronounce the second consonant at the start of the second block (넓은 said like 널븐)
If not, only one of the pair is pronounced. Usually it's the first (앉다 said like 안다) EXCEPT ㄹ followed by ㄱ,ㅁ or ㅍ(닮다 said like 담다 but 넓다 said like 널다).
and I have a question which confusing me so much. I remembered when we were studying 있다 and 없다, we use them to describe something too, I mean we built an adjective using them for example: 잭이 재미있다 which mean the book is interesting, interesting her doesn't it play the rule of the adjective too??? I hope someone could read this and give me a good answer .
