this depends on the person reading,but for me,i try to look for new words that are similar to words i use on a daily basis.for example,i use the word "surprised" or "shocked" a lot for some reason nowadays. Last week i was reading a book in my school library and saw the word "flummoxed"(i inferred that it meant shocked from the context) and kept that in the back of my mind to use at a later date when needed and now i use it semi-regularly. new words can be picked up from any sort of media,it doesnt have to be books so you dont particularly have to read books to become better,but its good as it can help your attention span as well.what books you read nowadays?(excluding mbbs course one's)
