Etymology

The word "fitful" originates from the Old English fitt, meaning "conflict" or "struggle," which later evolved to denote sudden bursts or spasms (e.g., "a fit of anger"). The suffix -ful (meaning "full of") was added in the 16th century to describe something characterized by irregular, abrupt movements or occurrences. The term vividly captures the idea of unpredictability, as if filled with sudden "fits."
