Word Origin for ameliorate

C18: from meliorate, influenced by French améliorer to improve, from Old French ameillorer to make better, from meillor better, from Latin melior


Ameliorate is often wrongly used where alleviate is meant. Ameliorate is properly used to mean `improve', not `make easier to bear', so one should talk about alleviating pain or hardship, not ameliorating it
