spurts

Spurt is a noun and verb used to describe a sudden, brief burst of liquid, gas, or activity. The plural spurts refers to multiple such bursts. In everyday language, a spurt can describe a jet of water from a hose, a short-lived surge of speed in an athletic effort, or a rapid, temporary increase in production, sales, or other measured activity. In science, spurts may denote brief, intense episodes in various processes, such as fluid jets or growth changes.

Growth spurts are periods of accelerated growth in humans. They commonly occur in infancy, school age, and puberty, when hormones such as growth hormone and sex steroids promote rapid increases in height and body size. Duration varies from weeks to several months; nutrition, sleep, and overall health influence timing and intensity. Other biological spurts may appear in plants or animals as temporary accelerations in development or reproduction.

The term spurt derives from the verb spurt, reflecting a sudden, forceful expulsion or eruption. In practical use, spurts are contrasted with sustained processes, highlighting their temporary and episodic nature.
