Korean is a very difficult language to learn. Here are a handful of the words that I've struggled to deal with.
I've written the Korean version phonetically.
Banana - ba-na-na
Juice - joo-suh
Internet - in-tuh-net-tuh
Shopping - shyo-peeng
Card - cad-uh
Building - beeld-eeng
Computer - com-pyoo-tah
Stress - suh-tuh-res-suh (say it fast)
I'll leave you hanging as to meanings of the following words: tel-leh-bi-syon, ra-dee-o, ah-ees-kuh-reem.
