Are you tired of having only ㅏ to work with? Would you like to buy some more vowels? Here are two more for free:
ㅗ, pronounced like the o in oh!
ㅜ, pronounced like the oo in moon. [The standard way of writing Korean using English letters, known as Romanization, uses the letter u to stand for this oo sound, and that's what we'll use from now on.]
Now we have to stack our consonants and vowels on top of each other if we wish to stay within the square box:
This syllable: 목 is pronounced mok with a long o, and it's the word for neck or throat.
문, meanig door, is pronounced mun with a long u.
Here is a word that has both horizontal and vertical vowels in it, with the square boxes shown: 누나, meaning elder sister, is pronounced nu-na.
Here's another word: 나무. It means tree. Can you figure out how it's pronounced? (Answer on next page).
