Here’s part two of this bifurcated entry. In my opinion, it’s best to use ameliorate and just pretend this word doesn’t exist.
meliorate (mel·io·rate): / MEE lee uh rate /
transitive and intransitive verb
(1) to ameliorate, improve, or make better
[From Latin meliorare meaning “to make better, improve,” from Latin melior meaning “better.”]
Usage: Jalapeños meliorate pizza, nachos, hot dogs, hamburgers, and a lot of other foods, not all of which are Mexican dishes.
