Which term describes the use of mild or vague language instead of direct terms?

The term that best describes the use of mild or vague language instead of direct terms is "euphemism." Euphemisms are often employed to soften the impact of what is being communicated, making it more palatable or socially acceptable. For instance, phrases like "passed away" instead of "died" serve to cushion the emotional weight of the message. This technique is commonly used in sensitive contexts to address topics that might be considered harsh or uncomfortable if expressed in blunt terms.

Understanding euphemism is important in advocacy and debate, as it highlights how language can be strategically used to influence perception and reaction. In contrast, terms like etymology focus on the origin of words, obfuscation refers to making something unclear or confusing, and exaggeration involves overstating facts, none of which directly align with the meaning of using mild or vague language to replace something more direct.
