IPA: /ˈfɪtfəl.nəs/
KK: /ˈfɪtfəl/
The state of occurring in irregular or intermittent bursts rather than continuously.
Her sleep was marked by fitfulness, waking up several times during the night.
Fitfulness → It is formed from "fit" (from Old English *fitt*, meaning a condition or state) and "-fulness" (meaning the quality of being full of). The word "fitfulness" refers to the quality of being in a state of fits or irregularity.
Think of being in a 'condition' ('fit') that is 'full of' irregularity ('-fulness'). This helps you remember that fitfulness describes a state of inconsistency or irregularity.
