What is Gyeongsang Satoori? After attempting to start to learn Korean I came across different ways to spell and pronounce words.

The different dialects can sometimes get confusing and I don't know which way to learn it.

Can someone please explain to me the difference between Gyeongsang/Busan Satoori and Gyeonggi/Seoul Satoori?

What makes them different?

Are their just different ways to say different words?
