What does fitful mean?
Fitful is an adjective describing something that proceeds in irregular bursts rather than steadily — active for a moment, then dormant, then active again. A fitful night's sleep is broken by repeated waking; a fitful breeze stirs the leaves now and then without ever settling into a proper wind; a project makes fitful progress through alternating spells of work and stagnation. The word derives from the older noun 'fit,' meaning a sudden burst or paroxysm of activity, combined with the suffix '-ful.' Its connotation is usually mildly negative or at least uneasy, suggesting restlessness, unreliability, or effort that never quite gains momentum. It appears frequently in literary and descriptive writing, particularly in connection with sleep, weather, light, and human endeavor, and its most celebrated appearance remains Shakespeare's phrase 'life's fitful fever' in Macbeth.

Etymology of fitful
Fitful was formed in English from the noun 'fit,' in its older sense of a sudden period or paroxysm of activity, combined with the suffix '-ful.' The word emerged in the early seventeenth century, with Shakespeare's use of 'fitful fever' in Macbeth (c. 1606) among its earliest and most famous attestations. It is thus a native English formation rather than a borrowing, and its relatives are the adverb 'fitfully' and the noun 'fitfulness.'
