This is an attempt to define the difference but even this tends to make the writer sound a bit like the mechanic where the author is the racing driver. I prefer to look at the difference in relation to the scope of the writing. What I mean by that is an author writes books, a writer writes everything and anything. It may seem a bit simplistic but with reference to myself I write novels, poetry, recipes, a diary and a blog. I have sold, and I'm still selling books that are all my own work, so to some degree I'm an author also. I just enjoy what I do.
Author vs Writer
We often use the words author and writer interchangeably. But indeed both these words are quite different. A writer is a person who writes a book, article, or any literary piece, while an author is essentially the person who originates the idea, plot, or content of the work being written. At times, the author and writer can be the same person. In case of an autobiography, a person writes about the own life. So the author is expressing his own thoughts and ideas. But in cases like biographies, the writer is not the author. The ideas of thoughts of another are being written.
Though the difference may not seem to be much, depending on the situation, the difference can be more. If you are writing a novel or short story based on a plot developed by self, you get to be known as the author of the novel. And if you are penning down someone else’s ideas or stories, you will be known as the writer of the work. Being a writer is at times easier than being an author. The reason being that an author has to create, develop, and communicate an idea, while a writer has to only communicate somebody else’s idea. An author may be excused if the writing skills are not that competent. But an author must have exceptional writing skills to be dominant in the field. Writing skills include the command over the language and the expressiveness with the play of words. These skills can be obtained through constant writing and may be an inborn talent in some. Only a skilled writer is capable of portraying ideas, events, and pictures through the mere use of words.Author
