Today's word

dyslogistic \diss-luh-JISS-tik\ - uncomplimentary

Logic would lead one to believe that "dyslogistic" is somehow related to the Greek word "logos," from which the words "logic" and "logistics" are derived. In actuality, however, "dyslogistic" is a 19th-century merger of the prefix "dys-," meaning "bad," and "eulogy," referring to an expression of praise. English jurist and philosopher Jeremy Bentham (1748-1832) often used "dyslogistic" in his writings as an adjective to convey dispraise or opprobrium. And even today the word is likely to be encountered in judicial and intellectual writings.

I'm thinking the roots of "eulogy" run closer to "logos" than the author is giving credit for.

And I really love this word.
