origin

The word of the day is “hapless.” Antonym: “hapful.”

“Hapless” came from the word “hap”, which meant:

one’s luck or lot.

Thus, “hapless” would mean luckless, or unfortunate, unlucky.

Etymonline.com:

“unfortunate,” c.1400, from hap (n.) in the sense “good luck” -less.

Although “hap” has the meaning of “occurrence, happening, event”, “hapless” came from “hap”‘s meaning of “luck”, not it’s other meaning(the above).
