    Note

    Here the luck belongs to the thing, not the person: a lucky mistake, a lucky cast, a lucky hour. Unlike the sense said of people, it describes what brings fortune or turns out well. A lucky mistake is simply one that worked out. Its synonym auspicious pulls toward hours and days that promise well, while Norman Lindsay's Age of Consent (1938) shows the everyday use: a "lucky chance" that kept a man from being out of pocket.
