What does fitfully mean?
"Fitfully" is an adverb describing action that proceeds in irregular bursts rather than a steady flow. To do something fitfully is to do it intermittently — starting and stopping, advancing unevenly, or flickering without constancy. The word attaches naturally to many contexts: rain that falls fitfully arrives in scattered showers; a fire burns fitfully when starved of fuel; an economy recovers fitfully when gains alternate with setbacks. Its second common sense concerns rest rather than effort: to sleep fitfully is to slumber badly, waking often and never settling deeply. This dual use — for both erratic activity and broken rest — gives the word unusual reach across descriptions of weather, work, machinery, and sleep. Its connotation is mildly negative, implying incompleteness or unease, which makes it useful for conveying struggle or instability without harsh judgment. Derived from the noun "fit", itself rooted in the idea of a sudden onset or paroxysm, "fitfully" preserves that older notion of spasmodic intensity in its very texture.
In an irregular or intermittent manner; in bursts with pauses between.
"The old engine ran fitfully, coughing to life and then dying again."
Restlessly or unquietly, especially of sleep marked by frequent waking.
"He slept fitfully through the storm, dreaming in fragments."
The word 'fit' behind 'fitfully' once meant a violent convulsion or seizure — so to sleep 'fitfully' originally carried something close to the sense of tossing and turning through small storms of unrest.

Etymology of fitfully
Fitfully derives from the adjective "fitful", formed from the noun "fit" — a sudden attack, convulsion, or burst of intense activity. The noun "fit" appeared in English in the Middle Ages; one strand of its origin lies in Old English "fit" meaning a conflict or struggle, though the sense of a bodily paroxysm was reinforced by related Germanic forms. By the early modern period, "fitful" described anything given to sudden, irregular onsets, and "fitfully" emerged as its adverbial form, first attested around the seventeenth century.
