If you understand the prepositions, you do not have to memorize idioms difficult and you can use the correct prepositions when you write English. This book explains the preposition to you with an easy-to-understand diagram. It was not easy to go to the contents of the prepositions when I was going to write a book. As you look at the books on published prepositions, the first explanation starts out plausibly, and you see that you are going to go back and eventually fall into your own error. I explained that if one of the words in a book starts with the original meaning it had when it first started, a similar meaning would be derived and spread there, and that argument was sufficiently persuasive. However, he insisted that he could not reveal the meaning of the first meaning properly, but he brought out the example sentence that was suitable for his explanations. On the other hand, the book was written as on, but on means on even though the first meaning of on is not up, even if the dog is tied up with a string on the tree, If you are on on or on when you are on the ceiling, you can find all the words that you can find.Yes. Then Ill do it! " I started thinking how to get direction. I am not a linguist, but if I was born and expanded in the first sense, I thought it might be like a child learning a language, and I started to sort it out according to it. The concept of language first caught by young children is a visible noun, the second is a moving verb, the third is a temporal word concept, and the fourth is a concept of an abstract word. , The same meaning continues in the sentence of movement, and continues to the sentence of time and abstract content, meaning that the meaning is derived and expanded, but the original meaning that was originally left is left.You can read the book lightly to understand it. Although English may not be easy yet, it is more important to understand progress along with translated Korean.Hopefully I will be rewarding if you can help a little with your English acquisition.
