flutter
word
Definition
To move lightly and quickly up and down or from side to side, like a bird's wings or a flag in the wind. It can also mean when your heart beats very fast because of excitement, fear, or nervousness.
Usage & Nuances
Used for soft, quick, irregular motions (wings, curtains, leaves, eyelids, heartbeat). Common in both physical and emotional contexts: 'fluttering heart', 'butterflies flutter', 'curtains flutter'. Not interchangeable with 'flap' (stronger) or 'wave' (smoother). Slightly poetic, rarely used for very strong movements.
