I am currently learning with the book "Elementary Korean" by Tuttle. According to the book, when ㅌ appears before 이, it should be pronounced as ㅊ, when it appears at the end of a morpheme or word (known as "palatalization to ㅈ", p. 43).
As far as I can hear, the audio recordings shippped with that book do that instead:
짙 + 이 is pronounced as [지티] (pretty sure here)
낟 + 이 is pronounced as [나지 ] (could also be [나치], my hearing might not be optimal).
Obviously, this is a contradiction to the statements in the book - could someone shed some light on this rule, when it is applied and how? Did I miss something blatantly obvious?
This is the exercise (8th and 14th entry):
Thank you very much!
