Here's why:
* "Ab" is often considered a prefix meaning "away from" or "off," but in this case, it's part of the Latin root "abrogare" meaning "to abolish" or "repeal."
* "-ate" is a common suffix indicating a verb, but it's also incorporated into the Latin root.
Therefore, "abrogate" is more accurately considered a single word derived from Latin, with no distinct prefix and suffix.
