According to Webster’s 11th Collegiate Dictionary:
¹author n [ME auctour, fr. AF auctor, autor, fr. L auctor promoter, originator, author, fr. augēre to increase — more at EKE] (14c) 1 a: one that originates or creates : SOURCE <software ~s> <film ~s><the ~ of this crime> b cap: GOD 1 2: the writer of a literary work (as a book)
²author vt (1596): to be the author of: WRITE <has ~ed several books>
writer n (bef. 12c) : one that writes: as a: AUTHOR b: one who writes stock options
¹book n [origins blah, blah, blah] (bef. 12c) 1 a: a set of written sheets of skin or paper or tablets of wood or ivory b: a set of written, printed, or blank sheets bound together into a volume c: a long written or printed literary composition d: a major division of a treatise of literary work (and many other known uses of the word “book”)
The point of this post is to show that whether you call yourself an author or a writer–they mean the same exact thing. Some out there think one is not an “author” until one is published, but I have authored 3 complete manuscripts with a beginning and an end. To me they are my books even though they aren’t published. I am a paid published writer of non-fiction articles. Either one of these accomplishments qualifies as a designation of writer and author.
I am the author of everything I write! 😉
