Educated individuals are no longer immune to the trappings of linguistic error and verbal ugliness. Particularly in the last few decades, educational systems have experienced a de-emphasis on grammatical rules and bylines of expression. Consequently students may learn to express themselves by using the first words that come to mind, and not those that are most lucid. Such linguistic carelessness may find its way through the mouths of journalists, teachers and politicians, only to reinforce and proliferate verbal errors.
Language alters with time. When old expressions and meanings die, new ones are born. Such evolution enriches a language. Freedom of expression without strict grammatical regulation, is a means by which individuals communicate more effectively and realistically. Such expression eliminates the need for elitist jargon.
