Word Confusion: Compose versus Comprise

Posted January 22, 2013 by Kathy Davie in Author Resources, Editing, Self-Editing, Word Confusions, Writing

Revised as of 22 August 2017

Admittedly, comprise is not used often. However, I do frequently find authors using compose when comprise would be the appropriate choice.

The distinction is in the parts. Compose uses parts to make a whole while comprise is a whole that includes parts.

Word Confusions…

…started as my way of dealing with a professional frustration with properly spelled words that were out of context in manuscripts I was editing as well as books I was reviewing. It evolved into a sharing of information with y’all. I’m hoping you’ll share with us words that have been a bête noir for you from either end.

    • It was so perfect to help explain such a, well, nebulous concept. Thanks very much for creating it! I hope it helps bring traffic to your site.

  1. I think you have it wrong in your header image. Four countries don’t comprise the UK; the UK comprises four countries. Four countries _compose_ the UK.

    To be sure, substitute “is made up of” for the word comprise. Four countries aren’t made up of the UK; the UK is made up of four countries.

    In the same vein, documents are not “comprised of” words; they are composed of them, and they are composed by people :D. And loosely, documents might comprise words, though comprise seems more directed toward a set of distinct items, versus a list of non-distinct items in a given order (like words in a document).
