Making the simple complicated is commonplace; making the commonplace simple, awesomely simple, that is creativity. (Charles Mingus, 20th century musician)
Have you ever read an article or book and wondered why the author chose to use arcane words (like that one) when he could have chosen a simpler one (like obscure), understood by everyone? Whether it’s college professors or elementary school teachers, their students will learn more effectively (and enjoyably, no doubt), if they use simple, understandable language.
My words are plain to anyone with understanding, clear to those with knowledge. (Proverbs 8:9)
