Answer 2 of 2 (Continuing from previous answer):
On the last one, be careful of the 받침 rules. (In case you're not familiar: In Korean, when one syllable ends in a consonant sound, and it is followed by a syllable that begins with a vowel sound, you always move the consonant sound terminating the first syllable to the beginning of the following syllable. So 받아 would be pronounced 바다). There are words such as "늙은" (old) where the first syllable actually ends in the ㄱ. If this ended with the first syllable, you would not pronounce the 'ㄹ' at all, but since the next syllable begins with a vowel, you pronounce it like '늘근'. In that case, the first syllable would end in the ㄹ sound in pronunciation. Since it is pronounced with one syllable ending in ㄹ and the next beginning with ㄱ, you would follow the rule of the ㄹ being followed by a consonant, and that would be pronounced with an 'L' sound like "neul-geun."
Hope this helps. I invite anyone to constructively critique my answer.
