Every job requires communication skill, but surely, there are certain positions that demand an excellent level of it. For example, a public relations officer will have to learn a high degree of public presentation and develop it in order to address issues in a clear, unambiguous manner. Being articulate in the English language (oral and/or written), for instance, shows that the individual can communicate ideas, concepts, framework, issues, products and services that a company is working on. Competently answering questions from internal and external audience members plays a vital function in determining whether a job needs excellent communication skill.

As regards the second question, as far as my research goes, no one is born with an excellent communication skill, as language is acquired and then learned through years of studying and interacting with people. Yes, there are people who are exposed readily to language inputs which predispose them to be more fluent and accurate with their word choice and grammar. Nonetheless, constant practice is, without question, an indispensable ingredient to having very good communication skill. As such, starting early will give language learners an advantage especially if they want to learn languages other than their mother tongue.

Thank you for your kind invitation. I leave this answer to the experts

Communication can always be improved by the help of specialist and with practice
