The final position in the Hangeul syllable block is the trickiest. When only one letter is present the syllable is straightforward, but sometimes two consonants can cluster together here. Not all letters can do this, and knowing how to pronounce the cluster is not necessarily straightforward since despite there being two letters, only one sound can be made. The question that many non-native speakers have (and even native speakers who have never learned Hangeul) is which one to actually say.
