This is really a great resource to learning ALOT of vocabulary quickly. Similar to the relationship that English shares with Latin, a large portion of Korean words are derived from Chinese. This book lays out some of the most common Hanja, using the Korean spelling. It also provides the English translations.
For example, the entry for 헉 (learning; study) has words like the following:
대학 - university (great + study)
학자 - scholar (study + person)
방학 - vacation (release + study)
입학 - entering school (entrance + study)
You will quickly realize that your vocabulary is bigger than you realize, and if you know pieces of words, they can help you guess at the meaning. And there are some cool words too.
One of my favorites:
대식가 - someone who really eats alot. I imagine it is kind of like calling someone a glutton.
대(great)
식(food) 식사, 식당...
가(specialist)
