This chapter shows how to use language that reflects the professionalism audiences expect of leaders. Many speakers try to bond through using overly casual or colloquial language in an effort to sound real. Audiences hold leaders to high standards. They expect professionalism from those whom they follow, and that behavior should be reflected in the words leaders use. Leaders recognize that they need to use language that is personal yet consistently professional. The chapter teaches the reader to walk this important line in his choice of words. The first step in using professional language is to recognize that what constitutes professional varies depending on where a person works. The chapter advises that people must know what constitutes appropriate language in their workplaces and occupation. They must find the middle ground between casual and formal and skip the swearing.
