Adjunct
Definition 1 of 4
Pro Tip 1/2
Enhancement Role
Used when something adds extra benefits, not just present for show. A well-made sauce is more than a garnish; it's an adjunct to the dish.
Pro Tip 2/2
Not a Necessity
Even though it's useful, an adjunct doesn't mean it's absolutely required. A sunroof is a nice adjunct in a car, but not a must-have.
