The person who is taking his vocabulary journal is considering in it some sort of better description of words that are in the vocabulary journal. It could have any words and usually it is used in primary school education.
The ones who are leading their vocabulary journal can include in it first of all, the definition of the word. Then, it can include an illustration of it(which is very helpful for the children). It can also include what part of speech is the word, their synonyms or antonyms and more.
My favorite writer is Stephen King. I suspect he gets a lot of inspiration from his enviroment. He writes a lot about his hometown of Maine and seems to get most of storylines from the silent town he resides in. Hope this helps!
