to work with? Would you
like to buy some more vowels? Here are two more for free:
, pronounced like the o in oh!
, 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: 
is pronounced mok with a long o and it's the word for
neck or throat.

, meaning door, is pronounced mun with a long u.
Letter-stacking rule: vowels that are "vertical", like, go to the right of the first consonant in your syllable. Vowels that are "horizontal", like
, go under the first consonant in your syllable. All of this is done to make sure that syllables fit into a square box.
, meaning elder sister, is pronounced nu-na.
Here's another word: 
. It means tree. Can you figure out how it's pronounced?
