vicious circle

A negative situation that is constantly maintained or worsened, rather than resolved. Underdeveloped countries are often stuck in a vicious circle of poverty that their citizens can never overcome. I use my credit card because I don't make enough money to pay my bills, and as soon as I get paid, any extra money goes toward my credit card bill. That vicious circle is why I'm constantly broke!

A series of events in which each problem creates another and worsens the original one. For example, The fatter I get, the unhappier I am, so I eat to cheer myself up, which makes me fatter yet-it's a vicious circle . This expression comes from the French cercle vicieux, which in philosophy means "a circular proof"-that is, the proof of one statement depends on a second statement, whose proof in turn depends on the first. One writer suggests that the English meaning of "vicious" helped the expression acquire its more pejorative present sense, used since 1839.
