Fluttery describes quick, light, irregular movements, like the way a butterfly's wings move or how a flag ripples in a gentle breeze. When something is fluttery, it trembles or waves with small, rapid motions.

You might notice a fluttery feeling in your stomach before giving a speech in front of your class: that nervous, jumpy sensation comes from tiny muscle movements inside you. Your heart might feel fluttery when you're excited or anxious. A bird's wings make fluttery movements when it hovers near a flower, beating rapidly but gently.

The word captures something delicate and unsteady. Curtains become fluttery when a breeze comes through an open window. A fluttery voice sounds shaky and uncertain, like someone trying not to cry or speaking when they're nervous. Leaves on certain trees, like aspens, are naturally fluttery because their stems are so flexible that even the slightest wind sets them trembling.
