Flutter vs. Angular — What's the Difference?

(of a bird or other winged creature) fly unsteadily or hover by flapping the wings quickly and lightly

Having, forming, or consisting of an angle or angles.

An act of fluttering

Measured by an angle or by degrees of an arc.

A small bet

Bony and lean; gaunt

To wave or flap rapidly in an irregular manner

Lacking grace or smoothness; awkward

To fly by a quick light flapping of the wings.

Rigid, stiff, and unyielding in character or disposition

To flap the wings without flying.

Relating or pertaining to an angle, or angles.

To move or fall in a manner suggestive of tremulous flight

Having an angle or angles; forming an angle or corner

To vibrate or beat rapidly or erratically

Sharp-cornered; pointed.

To move quickly in a nervous, restless, or excited fashion; flit.

Measured by an angle.

To cause to flutter

Lean, lank.

The act of fluttering.

Ungraceful; lacking grace.

A condition of nervous excitement or agitation

(figuratively) Sharp and stiff in character.

A commotion; a stir.

(organic chemistry) Composed of three or more rings attached to a single carbon atom (the rings not all being in the same plane).

(Medicine) Abnormally rapid pulsation, especially of the atria or ventricles of the heart.

(anatomy) A bone in the base of the lower jaw of many birds, reptiles, and fishes.

Rapid fluctuation in the pitch of a sound reproduction resulting from variations in the speed of the recording or reproducing equipment.

Relating to an angle or to angles; having an angle or angles; forming an angle or corner; sharp-cornered; pointed; as, an angular figure.

Chiefly British A small bet; a gamble

Measured by an angle; as, angular distance.

(intransitive) To flap or wave quickly but irregularly.

Fig.: Lean; lank; raw-boned; ungraceful; sharp and stiff in character; as, remarkably angular in his habits and appearance; an angular female.

(intransitive) Of a winged animal: to flap the wings without flying; to fly with a light flapping of the wings.

A bone in the base of the lower jaw of many birds, reptiles, and fishes.

To undergo divergent oscillations (potentially to the point of causing structural failure) due to a positive feedback loop between elastic deformation and aerodynamic forces.

Measured by an angle or by the rate of change of an angle;

(transitive) To cause something to flap.

Having angles or an angular shape

(transitive) To drive into disorder; to throw into confusion.

(intransitive) To be in a state of agitation or uncertainty.

To be frivolous.

To subject to a lie detector test.

The act of fluttering; quick and irregular motion.

A state of agitation.

An abnormal rapid pulsation of the heart.

An extremely dangerous divergent oscillation caused by a positive feedback loop between the elastic deformation of an object and the aerodynamic forces acting on it, potentially resulting in rapid structural failure.

(British) A small bet or risky investment.

A hasty game of cards or similar.

The rapid variation of signal parameters, such as amplitude, phase, and frequency.

To vibrate or move quickly; as, a bird flutters its wings.

To drive in disorder; to throw into confusion.

The act of fluttering; quick and irregular motion; vibration; as, the flutter of a fan.

Hurry; tumult; agitation of the mind; confusion; disorder.

The act of moving back and forth

Abnormally rapid beating of the auricles of the heart (especially in a regular rhythm); can result in heart block

A disorderly outburst or tumult;

The motion made by flapping up and down

Move along rapidly and lightly; skim or dart

Move back and forth very rapidly;

Beat rapidly;

Wink briefly;
