Showcase - parsimonious, erudite - Mrinalini

Erudite

My mother is very erudite. She answers all the questions I ask her. She has won many scholarships in her school days. I asked her many difficult questions which I took from the internet. She answered all of them correctly. My mother is really a very erudite person.

Parsimonious

My father does not buy me all the things I want. He does not give me enough  pocket money. He always wants to save his money and does not want to spend it. He is truly a parsimonious person.
