  • To use advertising copywriters as any kind of benchmark for educated grammar, let alone literacy, would be downright laughable if it weren't so absurd. Today's copywriters inspire an imaginary essay title: "How Has Advertising Copy Gotten so Rotten?" I see their faux pas every day, including a Travelers Insurance TV commercial that displayed the company's tagline, "In-synch." The hyphen is misplaced, unless we think comparable phrases should be hyphenated all of a sudden, such as "in-tune" or "in-place." It's a verb phrase, not a compound noun. While any absence of grammatical grace in ad copy often can be attributed to the "creative" staff's penchant to go for attention-getting effect, the "in-synch" example doesn't accomplish anything that a corrected, hyphen-less display wouldn't also effect, so the only conclusion is that nobody -- NOBODY -- at the agency or client was exactly an honors English student and can't distinguish between a verb phrase and a noun. As a copywriter would say, "Amazing!"

  • "The divine is God's concern; the human, man's. My concern is neither the divine nor the human, not the true, good, just, free, etc., but solely what is mine, and it is not a general one, but is -- unique, as I am unique. Nothing is more to me than myself!"

  • Cheers to that! Uniqueness is inmeasureable....

  • Listen up, peeps. Unique means "unparalleled, one of a kind". So, something is either unique or it isn't. It's never is "most unique" or "very unique" or "pretty unique". Uniqueness cannot be qualified. If you ever feel compelled to do so, you are probably searching for the word "unusual" instead.
