覚え方のコツ Memory Tip
原形 flutter に -ing を付けた現在分詞・動名詞で、語末を重ねず fluttering、発音は /ˈflʌtərɪŋ/。風を受けた旗・カーテン・紙や、素早く動く羽を思い浮かべる。flickering が光の不規則な変化なのに対し、fluttering は軽い物の小刻みな動きが中心。
Take the base verb flutter and add -ing: fluttering. No consonant is doubled. Picture a flag moving in a breeze, a curtain beside an open window, or a small sheet of paper being carried across a path. The central image is repeated, light movement caused by air or rapid wing action. Compare it with flickering: a light flickers when its brightness changes irregularly, while a flag or wing flutters when it physically moves. Learn common combinations such as fluttering flags, fluttering wings, and paper fluttering in the wind.

fluttering の語源・成り立ち Etymology
中英語flutterenに由来し、古英語で「漂う」の語根に反復の接尾辞が結合しました。軽い動作が連続する響きが、小刻みに動く羽や旗の「はためく」イメージに直結します。同語根の単語にfloat（浮かぶ）やflitter（ちらつく）があります。
Fluttering is formed from flutter plus -ing. Flutter comes from Middle English flutteren and belongs to a group of Germanic expressive verbs suggesting repeated light or rapid movement. It has been associated with other movement words, but its exact deeper formation is not completely certain. The suffix -ing marks an ongoing action or turns the action into a gerund, while preserving the sense of repeated gentle movement.
