Pure luck refers to an occurrence that was entirely due to chance, with no connection to skill, effort or preparation. Some synonyms of pure luck include chance, fortune, coincidence, fluke, accident, happenstance, blessing, stroke of luck, serendipity and providence. Each of these words implies an event that was beyond one's control, but with different nuances. "Chance" and "fortune" can be used for both positive and negative events, while "coincidence" and "happenstance" suggest a random meeting or occurrence. "Fluke" and "accident" suggest a surprising twist of fate, while "blessing", "stroke of luck" and "providence" imply a positive outcome. "Serendipity" suggests a happy accident that leads to a discovery or a new opportunity.
