Hyperbole engaged in consciously to achieve a desired effect can be, as we have noted, a useful rhetorical tool. Indeed, its use in this manner is sometimes called "exaggeration in the service of truth." However, there's much to be said for restraint of tongue and pen, and restraint refers not only to what we say but also to how we say it. It is possible, believe it or not, to be emphatic without indulging in overstatement; it is possible to be forceful without exaggerating.
The Grammar Curmudgeon
When you see the veins popping out of my neck, that's an exclamation point.
Don't mess with me. I've got tanks.
Canada's first female Prime Minister
"Very" is the most useless word in the English language and can always come out. More than useless, it is treacherous because it invariably weakens what it is intended to strengthen. For example, would you rather hear the mincing shallowness of "I love you very much" or the heart-slamming intensity of "I love you"?
I write from my heart, so everything I say, I say with force.
The force of what was called Panther rhetoric or word mongering resided not in elegant discourse but in strength of affirmation (or denial), in anger of tone and timbre. When the anger led to action there was no turgidity or over-emphasis. Anyone who has witnessed political rows among the Whites will have to admit that the Whites aren't overburdened with poetic imagination.
Words, like cannon balls, should go direct to their mark.
Once again, you show all the sensitivity of a blunt axe.
Be your strong and simple words Keen to wound as sharpened swords, And wide as targes let them be, With their shade to cover ye.
In the modesty of fearful duty, I read as much as from the rattling tongue of saucy and audacious eloquence.
Write as the wind blows and command all words like an army!
In general the languages of most unpolished people have a great force and energy of expression; and this is but natural. Uncultivated people are but ordinary observers of things, and not critical in distinguishing them; but, for that reason, they admire more, and are more affected with what they see, and therefore express themselves in a warmer and more passionate manner.
