Euphemisms, Loaded Words, & Double-Speak

A euphemism is a word or phrase used in place of another word or phrase.  Often euphemisms are used in order to mislead, to confuse, or to neutralize the reaction of an audience.  

Loaded words are words used to engage the emotions of the reader or listener.  These are words that have strong connotations.  Some loaded words (especially the ones with positive connotations) are also euphemisms.

Double-Speak is the use of words or phrases such as "War is peace."  Double-speak is the use of words in an attempt to make something untrue, true.
