IPA: /ˈflʌfiər/
KK: /ˈflʌfiər/
Having a light, soft, and airy texture; more so than something that is fluffy.
The new pillow is fluffier than the old one, making it much more comfortable to sleep on.
Fluffier → It is formed from "fluff" (originating from the Middle English *fluffe*, meaning soft or light material) and the suffix "-ier" (indicating a comparative form). The word "fluffier" means having more fluff or being softer and lighter in comparison to something else.
Think of something that is 'soft' ('fluff') and 'more' of it ('-ier') — that's why fluffier means more soft and light.
