AU'THOR, noun [Latin auctor. The Latin word is from the root of augeo, to increase, or cause to enlarge. The primary sense is one who brings or causes to come forth.]

1. One who produces, creates, or brings into being; as, God is the author of the Universe.

2. The beginner, former, or first mover of any thing; hence, the efficient cause of a thing. It is appropriately applied to one who composes or writes a book, or original work, and in a more general sense, to one whose occupation is to compose and write books; opposed to compiler or translator.

AU'THOR, verb transitive To occasion; to effect. [Not used.]
