* Root word: The word "devastation" comes directly from the Latin word "devastare," meaning "to lay waste" or "to destroy."
* No separate prefix: While "de-" can sometimes act as a prefix meaning "away from," it's not used independently in "devastation." It's part of the original Latin root.
* No suffix: The ending "-ation" is a common suffix in English, but it's already integrated into the meaning of "devastation" as a process of destroying.
Therefore, the word "devastation" is best considered as a single, unanalyzable unit in terms of prefix and suffix.
