A miser is someone who is infatuated with the past, and is grumpy about the present, (compared to depressive, or someone who is infatuated with the future, and depressed about the present), so when did it come to mean someone who is a cheapskate and stingy over money?
miser is not the same as “greedy old penny-pincher”
