The word "aflutter" is artfully employed in literature to convey both literal and metaphorical states of movement and emotional agitation. It vividly describes the physical trembling of objects—a scarf teased by a brisk breeze ([1]), or flags and streamers animatedly dancing in the wind ([2], [3])—while also evoking the fluttering of hearts filled with anticipation, excitement, or tender affection ([4], [5], [6], [7]). In some passages, the term enriches the narrative with an air of restless energy, as characters experience a sudden surge of hope or nervousness ([8], [9]), whereas in others it accentuates a delicate, almost whimsical quality, setting an atmosphere that is both ephemeral and dynamic ([10], [11]).
