#The etymology study method is a multiplication method, not an addition method, where you use the etymology as a hint and then think of related words one by one.
The etymology learning method introduced in this book helps you memorize words by associating them with their etymology as a clue.
Then, you will be able to memorize related words one by one, which will increase your vocabulary by leaps and bounds.
If memorizing words one by one is addition, then learning etymology is multiplication, so naturally the learning speed is bound to be different.

#An etymology picture book that offers the fun of reading a comic book with fun illustrations.
This book expresses each word with an illustration, allowing readers to intuitively understand the meaning of its etymology.
You can experience building a three-dimensional vocabulary network in your head through the power of images through illustrations and etymologies.
Information absorbed with an image will be strongly imprinted and remain in the memory for a long time.


There is no royal road to studying, but there is a 'proper way to study'.
If you find the 'proper way to study', you can see results that exceed your expectations while saving time, effort, and even money.
The 'Thanks to' series was born from these thoughts: 'Isn't there a way to study a little easier and more fun without getting stressed?', 'If I learn something important about studying, won't I be able to experience studying becoming much easier?'
I wanted to give the gift of the thrill of making studying easier and more fun.

The benefits you can gain from learning etymology are as follows:

1.
Words with the same root (etymology) follow one after another.
2.
Knowing the etymology allows you to understand the exact meaning and nuance of a word.
3.
It is memorable for its etymology and illustrations.
4.
Studying English becomes easier and more motivating.

5.
Words are remembered for a long time, and vocabulary is increased just by looking at them.
6.
You will be able to infer unfamiliar words without being flustered.
There is no need to mechanically memorize words anymore.
Because you can naturally learn the meaning of a word through its etymology, and you will be able to infer its meaning without being confused when you come across a similar word.

The process of learning about etymology is also a process of repeatedly discovering connections between words.
The pan in company means 'bread to eat', the pare in compare means 'pair', and the min in minute means 'mini', meaning miniature.
As you read the book and learn about these things, you will feel endless interest.
Curiosity is a source of motivation.
I am confident that reading this book will make studying English words easier thanks to their etymologies and turn studying into a pleasure.
