Hapless means exactly what you'd expect it to mean: "without hap"—hap being another word for fortune or luck. Hap comes from the Old Norse word for "good luck," which is also the source of happen and happy. English has several words to describe those lacking good fortune, including ill-starred, ill-fated, unlucky, and luckless, a word formed in parallel to hapless by adding the suffix -less. Ill-starred suggests bringing calamity or the threat of a terrible fate ("the ill-starred year the Great Depression began"). Ill-fated refers only to being doomed ("the ill-fated voyage of the Titanic"). Unlucky and luckless usually apply to a person or thing notably or chronically unfortunate ("an unlucky slots player," "some luckless investors swindled in the deal"). Hapless is often imbued with a touch of pity, humor, or both for those to whom it refers, as in "a hapless goalie who couldn't block a shot to save his life."
