Febri's right - there's a huge difference between "wanita muda" and "wanita mudah"! :) The other pairs are definitely different. Even to me as a native English speaker, it's obvious that "hutan" and "hutang" have different pronunciations.

There all different.. for example muda (young) n mudah (easy).. the stressing point is 'H' if U forgot said it will be different..in english if I not mistake it called bound morfem..

Yes, those all have different sound. You need to spell the last letter.

yeah! of course those words have different pronunciation. Try to listen Indonesian native speaker, you will get that ;)
