Which one do I use? 무엇 or 무슨? I'm still a beginner in Korean and I've come across a bit of a stumbling block when it comes to the word 'what' I was taught to use 무엇 for questions like 'what is this?' or ' what does your dad like?' (이것은 무엇 입니까? / 아버지는 무엇을 좋아합니까?) as it takes the place of a subject/object in a sentence, but I've just come across the question 'what sport do you like?' (무슨 운동을 좋아합니까?) and I'm confused as to the difference? I'm learning in high formal so I can avoid offending anyone but I do understand low/high informal. Any clarification would be well appreciated.
