If you are experiencing malaise, chances are you are feeling blue or looking green. Malaise is a slump; you're not feeling your best — either mentally or physically.
Mal is French for "bad," and aise means "ease." When experiencing malaise, ease yourself down on the couch to recover. Malaise is frequently used figuratively to describe slumps that other things go through as well. The 20-year economic malaise in Japan is one example, but you'll also hear of educational malaise, political malaise, and even "a general malaise." Wherever you turn, there's malaise.
