Yes
Not to the you're stupid part to the hyeong is another transcription of hyung part
Ahh ok ahahah thx
Its written Hyeong (형) but it's translated to Hyung in English. This is to make it easier for people who don't speak Korean to pronounce it the correct way! It's the same with Nuna (누나), which in English is spelled Noona, Eonni (언니) in Englished is pronounced Unnie! Oppa (오빠) is written how it sounds! You're not stupid its just a learning curve between translating between Korean and English.
Oooh interesting, I didn't know this!
Is hyeong another transcription of hyung?
