ㅎ (called 히읗, [hee ut]) sounds like the "h" sound in English. For example, 하다 sounds like [hada], and "hand" can be written as 핸드 in Korean. But this clear "h" sound is made only when it is at the start of a word and pronounced with a vowel following it. If ㅎ is at the bottom position (받침), or at the syllable start position after a syllable with a 받침, it is either muted or reduced to a mere effect on the preceding or following syllable. For example. - 이하 -> [이하] (normal sound after a syllable ending with a vowel) - 좋아 -> [조아] (ㅎ at the bottom position is muted before a vowel) - 좋다 -> [조타] (ㅎ at the bottom affects the next syllable by transferring the ㅎ sound - 다 becomes 타) - 묻히다 -> [무치다] (ㅎ at the start position affects the preceding syllable by transferring the ㅎ sound) Details of such pronunciation effects can get complex. it takes studying and practicing to master them. If this is not what you were wondering about, please ask again.
