Maybe, by consulting Dr. Webster.
Another example, a speech is being recited in a fact that it's so impressive in a sense the topic but it was redudantly saying a single idea. Hello, there is no barrier of communication is occurring to apply the principle of redudancy. The barrier is the word itself. Centain though might make the listener dizzy of the cycle of your very INTERESTING topic and vomit all the things he consumed from your piece.
Also in writing, it may occur. Sometimes, there are a lot who is so fond of using superflous sclerous and noxious stated words only to impress their readers to let them know that they're intelligent, but actually it's the wide vocabulary that is being used not your style of writing. It's nice to be a vocabularitic person but it's not nice to make every readers of your article suffer from anaemic.
