Verbal communication can vary among different age groups, genders, and social circles. As people age, physical changes can make communication more difficult. Males and females also tend to use language differently, with males focusing more on exerting control and status while females seek to create relationships. Groups develop their own specialized vocabularies like slang, jargon, and cant that are only understood among members and help reinforce their identities. Examples include youth slang terms, criminal lingo in the mafia, and professional jargon.
