Tautology. The "over" part is already part of the definition of
"exaggeration".
Yet another tautology. Unless, of course, you think that a moron
is anything other than idiotic.
Do you mean "unbearably poor command of English"? Please do
express yourself clearly.
Oh dear, oh dear, oh dear. I sincerely hope that was a
typo.
And how, pray tell, does one pluralise comprehension?
Pot, kettle, glass houses, stones, you know the drill.
