Loaded Words

Loaded words or loaded language describes the misleading use of emotionally loaded language in order to win an argument.

Besides a word's definition, most words have a connotation that implies that its subject is either good or bad. For example, both the words "cabin" and "shack" mean basically the same thing, but one word has a positive connotation and the other has a negative connotation. Using a loaded term by itself isn't fallacious, but using loaded terms as a basis for an argument is. Using a loaded term to imply that the subject in question is bad when the point of your argument is that that its bad is just another form of Begging the Question.
