Euphemisms and phenomenon of political correctness

Euphemism, as is known, is a word or phrase used to replace an unpleasant word or expression by a conventionally more acceptable one, for example, the word 'to die' has bred the following euphemisms: to pass away, to expire, to be no more, to depart, to join the majority, to begone, and the more facetious ones: to kick the bucket, to give up the ghost, to go west. So euphemisms are synonyms which aim at producing a deliberately mild effect.
