Hyper - beyond the ordinary - hyperactive (a person who is very active; more active than other people), hypersensitive (a person who is very sensitive; extra sensitive to things)

il-, in-, im-, ir- = illogical (not logical)
insufficient (not sufficient; not enough) impossible (not possible)
irresponsible (not responsible)

Poly - = many - polyglot (a person who speaks many languages)
polygon (a shape with many sides and angles)

Post - = after - postseason (after the regular season)
postscript (PS; additional remarks at the end of a letter)
