It really is okay to use certain words even if a number are overused and overhyped. A few people I was on a course with yesterday mentioned a few cliches they hate; innovative, unique and community to name but a few. These words including creative, ideas, engaging, diverse, vibrant, inspirational and social are great explanatory words.
Use these words but present them in context. The reason people get bored with them is because we haven’t done our job and made them tangible. There is nothing wrong with using the phrase cutting edge’ if you are. The problem occurs when you are not. Use the word landmark or the best only if you have independent testimony to back that up. If you took all of these fabulous words away, what would we have left? Mundane, flat, uninspiring words.
