Did you know?

Ameliorate traces back to melior, a Latin adjective meaning "better," and is a rather formal synonym of the verbs better and improve. When is it better to use ameliorate? Allow us to improve your understanding: if a situation is bad, ameliorate indicates that the conditions have been made more tolerable. Thus, one might refer to medicine that ameliorates pain from an injury, a loss of wages ameliorated by unemployment benefits, or a harsh law ameliorated by special exceptions. Improve and better apply when something bad is getting better or being made better (as in "the weather improved" or "she bettered her lot in life"), and they should always be chosen over ameliorate when something good is getting better still ("he improved his successful program," "she bettered her impressive scores").
