Usage

What does flutter mean? To flutter is to wave, flap, or toss, usually in reference to wings. The baby robin fluttered its wings as it prepared to fly from the nest for the first time. To flutter is to move in a quick, irregular motion or to vibrate, as when a flag flutters in a small breeze. Often, the difference between flapping and fluttering is that fluttering wings move in an irregular pattern or so fast that you cannot distinguish individual flaps. A flutter is the movement of fluttering, as in The flutter of a hummingbird’s wings is so fast that it creates a buzzing sound. A flutter is also a figurative term that describes a moment of nervousness, such as you might feel before a big exam. Some people describe it as feeling like butterflies fluttering in their stomach. A fluttering stomach is a nervous one, perhaps feeling slightly queasy. Other people describe such a feeling as a fluttering heart, particularly when they feel nervous about someone they have romantic feelings for. This, too, is figurative. In medicine, flutter is used literally to describe an irregular heartbeat, often in the term atrial flutter, which can cause irregular blood flow and different issues in the body. If your heart flutters and it’s not temporary nervousness, you should tell your doctor. Example: I always get a little flutter the night before a performance.
