Did You Know?

Ameliorate traces back to "melior," the Latin adjective meaning "better," and is a synonym of the verbs "better" and "improve." When is it better to use "ameliorate"? If a situation is bad, "ameliorate" indicates that the conditions have been made more tolerable. Thus, one might refer to drugs that ameliorate the side effects of chemotherapy; a loss of wages ameliorated by unemployment benefits; or a harsh law ameliorated by special exceptions. "Improve" and "better" apply when what is being made better can be good or bad (as in "the weather improved" and "she bettered her lot in life"), and they should certainly be chosen over "ameliorate" when something good is getting better still ("he improved his successful program"; "she bettered her impressive scores").
