Corollary
Etymology
From Latin "corollarium," which meant a small garland or a gratuity, literally "money paid for a garland," from "corolla," a diminutive of "corona," "crown." The sense was of a little something extra given beyond what was owed. Mathematics borrowed the image for a result that comes as a bonus, following almost for free from a theorem just proved.
noun · /KOR-uh-lair-ee/
A proposition that follows readily and with little additional proof from one already established.
What it names
The free consequence — the second truth you get thrown in once the first is settled, which is why spotting a corollary can save you an entire second argument.
Example
If the team can’t agree in a room together, a natural corollary is that a remote setup won’t fix the real problem.
Related idea
A corollary follows loosely and cheaply from a result; an inference is the broader act of drawing any conclusion from evidence, sound or not.
