For korean thats exactly the case, they are groups of letters, its not like Kanji or Chinese, which is why it's considered one of the easier east asian languages. IIRC you start from the upper right and work your way left, then down.
If you look at the korean alphabet:
You can see that each word is broken up into consonants and vowels just like in English. If I remember right Korean also has something similiar to Kanji for words though.
Go read the wiki, you'll see that korean has tons of loanwords, which most are from English so there's lots of cognates to help you remember stuff.
