Early on in my Korean studies, I learned that in multi-syllabic words, the first consonant of a subsequent syllable is typically tensed (된소리) if the preceding syllable ends in a consonant (받침).
Why is it that in the word,
현장, 장 is not pronounced 짱 to make it
현짱? I realize there are exceptions to the rule, but they seem to be very frequent.
Conversely, there are words that have a second syllable that is tensed, even if the preceding syllable does not end in a consonant.
Is there a rule here as well?
