What does fluttering mean?
Fluttering denotes a quick, light, and irregular kind of movement — the motion of butterfly wings, a banner in the wind, falling leaves, or a piece of paper caught in a draft. It functions chiefly as the participle of the verb flutter, but it can also act as a noun describing that wavering motion itself. Beyond the physical sense, fluttering is widely used to describe internal sensations: a fluttering pulse before public speaking, a flutter of excitement on receiving good news, or the flutter of attraction. In these uses it conveys delicacy, nervous energy, or heightened emotion, which makes it a favourite word in descriptive and romantic writing. Its associations are almost always gentle and rhythmic rather than violent, distinguishing it from harsher kinds of shaking or turbulence.
To move with quick, light, irregular motions, as wings, flags, or lightweight material does.
"Moths were fluttering around the porch light all evening."
A rapid, wavering motion, especially one made by something light or airborne.
"We could see the faint fluttering of a white flag above the ridge."
That nervous 'fluttering' in your stomach before big moments is real physiology — blood being redirected away from your gut by adrenaline.

Etymology of fluttering
Fluttering comes from the verb flutter, which traces back to Old English forms meaning to float about or fly unsteadily, built on the Germanic root underlying words like float. The word belongs to the large Indo-European family of terms derived from the root *pleu-, meaning to flow or float, which also gave rise to Latin-derived words such as flotation and flotilla. It has carried its sense of light, wavering motion since the earliest English records.
