"이 문은 잘 안 닫혀요."

Translation: This door does not close well.

[a.charmedlife]

What will the sentence be like for "This door is not closed well"?

[dongsang]

이 문은 잘 안 닫혀있어요.

[YunisR]

Why does 닫혀요 sound like 다쳐요? Shouldn't it be pronounced as 다텨요 because of the ㅎ?

[BarAdal3]

Nope, that's almost like a phonetic rule in Korean. When ㅌ is in final position and is followed by 이/히 or any of the diphtongs since they also include 이 because 여=이+어 for example, it is pronounced as ㅊ . Another example to this phenomenon is 같이. ( pronounced [가치] )

[YunisR]

Yes I know that, but this is not ㅌ it's a ㄷ. Shouldn't it sound like ㅌ?

[pluureng]

1. ㄷ + ㅎ = ㅌ
2. ㅌ + ㅕ = 쳐

[josueetcom]

For ㄷ and ㅌ and other ㄷ batchim combined with 히 or any other ㅎ + Y vowel (e.g. 혀) produce a 치 like sound. E.g.

ㄷ + 히 = 치

ㅌ + 혀 = 쳐

It's called Palatalization. You can read more about it and other Batchim rules here:
