Did You Know?

Someone feckless is lacking in feck. And what, you may ask, is feck? In Scots—our source of feckless—feck means “majority” or “effect.” The term is ultimately an alteration of the Middle English effect. So something without feck is without effect, or ineffective. In the past, feckful (meaning “efficient, effective,” “sturdy,” or “powerful”) made an occasional appearance. But in this case, the weak has outlived the strong: feckless is a commonly used English word, but feckful has fallen out of use.
