Misunderstandings are natural when learning a new language - but here are a few things you should NOT be mixing up :)
술 and 물
(sool and mool)
술 (sool) - Alcohol
물 (mool) - Water
Imagine: You go to get breakfast and you ask them "can I have some alcohol please?"
똑똑해요 and 뚱뚱해요
(ddohk-ddohk-hae-yo and ddoong-ddoong-hae-yo)
똑똑해요 (ddohk-ddohk-hae-yo) - Smart
뚱뚱해요 (ddoong-ddoong-hae-yo) - Fat
Imagine: You try to compliment someone for being smart and you call them "really fat" instead!
아빠 and 오빠
(ah-ppa and oh-ppa)
아빠 (ah-ppa) - Daddy
오빠 (oh-ppa) - Older brother (guy who is slightly older than you)
Imagine! Talking to your boyfriend or older guy friend from school and you accidentally call them "daddy!"
