Every word has a nuance. Comparing English and Japanese, the details of nuances are not the same. I bought an English combinatory dictionary, and I realized how necessary the English combination rule is. 

Not only that, combinations of sentences are also important. These English rules are stricter than I thought.

It is possible to ignore the rules to make understandable English sentences, but nuances take a leading part to make an impression. It must take me a long time to comprehend English nuances. The challenge for me is to find ways to study them. I want to improve step by step.
