There is an ongoing discussion on some of these threads about whether the K at the end of the word is pronounced in words like 'tidak'.
Here, the K sounds like a glottal stop. But in other cases it does seem like it is just plain missing. And in still other cases, I hear the K clearly.
I'm hoping to be able to zero in on some rules about why this happens when. Maybe it's just different in different areas of the country.
