This section gives some idiomatic vocabulary in English, as a blog, or list to which I regularly add. This vocabulary is also given (in more detail) in the page ‘Idiomatic Vocabulary’ (under the ‘Vocabulary’ Section). So, you have the same input twice, since both forms can be convenient.
However, if you are accessing the information here, it is very important that you go to the ‘Idiomatic Vocabulary’ Section to read the introduction – as there are rules and issues about idiomatic vocabulary which you should know.
