Affirmator

Part of speech: noun

Definitions

1. One who asserts or confirms the truth or validity of a statement or belief; a person who provides positive support or endorsement; one who upholds or maintains the correctness of a proposition
2. Someone who expresses agreement or validation of a claim or idea; an individual who offers assurance or backup for a statement; a party that supports or ratifies a position or judgement
3. An entity that declares a fact to be true or legitimate; a person who provides confirmation or affirmation; one who defends or asserts the accuracy of an assertion

Etymology: Its core is the Latin "firmus," meaning "firm" or "steady." Adding "ad-" ("to") gave "affirmare," which meant "to make firm" or "to strengthen," and only later came to mean stating that something is true. An affirmator, then, is literally someone who makes a claim firm by backing it up. The ending is the agent suffix "-ator," which Latin used to turn verbs into nouns for the doer of an action, as with "creator" from "creare." English formed the noun on that pattern, so the word's structure is transparent: affirm plus the suffix for one who performs the action. It is a rare, formal term, mostly found in older or technical writing.
