Pronoucing some characters

My friend was looking at my blog posts for korean, and he said I did not make one for the pronoucion of some of words.

When a consonant ends a syllable, like the '한' in '한국' ends with the consonant 'ㄴ', when it is like this and the next syllable starts with the consonant 'ㅇ', then the consonant that ended the syllable is carried over to the consonant 'ㅇ'.
Example: 일월(eel-wol) the first syllable has three characters in it, and it ends with a consonant, and the beginning to the second syllable is the character 'ㅇ', meaning that now the ending consonant from the first syllable with replace the character 'ㅇ' when pronoucing, it would sound like 이뤌(ee-lwol), not like 'eel-lwol'.
Other example: 삼월(sahm-wol) but pronouced as 'sa-mwol'

Here is a example that my friend told to do, he said it would be easier to learn with this example since it is a well known song. haha
Song name is 산소 같은 너(san-so gat-eun neo) by SHINee, but during the song they pronouce it as 'san-so ga-teun neo'(산소 가튼 너), this is because the syllable '같' ends with a consonant while the next syllable starts with the character 'ㅇ', so the consonant 'ㅌ' will replace the beginning of the next syllable when pronoucing.
This is ONLY when a syllable ends with a consonant and the next syllable starts with 'ㅇ', if the first syllable ends with a vowel, then it does change when pronoucing, even if the next syllable starts with 'ㅇ'.


Pronouion of some consonants:
When some consonants are the last character of a syllable, they are pronouced different.
Here they are:
ㅂ - like the letter 'B'
ㅈ - like the letter 'T'
ㄷ - like the letter 'T'
ㄱ - like the letter 'K'
ㅅ - like the lettet 'T'
ㅁ - like the letter 'M'
ㄴ - like the letter 'N'
ㅇ - like saying 'NG'
ㄹ - like the letter 'L'
ㅎ - like the letter 'T'
ㅋ - like the letter 'K'
ㅌ - like the letter 'L'
ㅊ - like the letter 'T'
ㅍ - like the letter 'P'
Same thing goes for the double consonants.

Hope this helps. ^^
