Unlucky

1. Not lucky; not successful; unfortunate; ill-fated; unhappy; as, an unlucky man; an unlucky adventure; an unlucky throw of dice; an unlucky game.
2. Bringing bad luck; ill-omened; inauspicious.
3. Mischievous; as, an unlucky wag.

This word is properly applied to incidents in which failure results from chance or fortuity, as in games of hazard, rather than from lack or feebleness of effort.
