What is the difference between “Hyperbole" AND "Euphemism"?

By Ranjana S.

»»»Hyperbole:

Hyperbole means exaggeration and by this figure things are represented as greater or less than they really are.

• When Kate smiled all the world was gay.
• I have not seen him for ages.
• The little girl wept oceans of tears.
• I thought ten thousand swords must have leapt from their scabbards to avenge even a look that threatened the queen with insult.

 »»» Euphemism:

By this figure we express something unpleasant or delicate or blunt in a mild and gentle way. This figure of speech is adopted to refrain from offence and is prompted by kindly feeling.

It is very often heard "passed away" or "fallen asleep" in common parlance. Similarly "to put away" is a mild term for "murder".
