Bilingual means you know two languages fluently. Like you can speak English and Spanish with no problem.
ethical communication is when you can speak different languages, it is just like bylingual
launguage is a tool subject because you need it to go places in life ! .... everyone wants to be bylingual and talk more then one language , it helps with jobs and it also helps with communication , launguage is so important .. but i think it should be taught more in schools , 2 hours about lanuguage .. and not only french ! , spanish , chinese , greek etc.
