I am looking an adjective which can be used to describe people who know a bit of everything , somebody who is not superficial in term of general information irrespective of someone's age.
I'd rather not use the word intellectual because it depicts an academic or philosopher who is very good at the area they the work area in my mind.Can we call a college guy as intellectual just because he reads a lot and knows pretty much something on everything?
I'd rather not use the word well-rounded because it includes someone's sportive activities but I am asking more about knowledge.
Maybe a word which can be used by someone to describe themselves who dare to attend " who wants to be millionaire" contest ?
