Which of the following is not a principle of effective word selection?

Using jargon is not a principle of effective word selection because it can create barriers in communication rather than facilitate understanding. Effective communication prioritizes clarity and accessibility, which means that word choices should be tailored to the audience's level of comprehension and familiarity with the subject matter. Jargon, which often includes technical terms specific to a particular field, can alienate those who are not part of that field or who may not have expertise in that area, ultimately impairing the message's effectiveness.

In contrast, being specific, emphasizing positive words, and avoiding clichés are recognized strategies for improving clarity and engagement in communication. Specific language helps to paint a clear picture and convey precise meaning, positive words can enhance the tone and encourage a favorable reception, and avoiding clichés ensures the message remains fresh and impactful rather than redundant or vague.
