The Telegraph has a new and very pertinent TVC - which is both, quite "obvious" but also with that "why didn't I think of it before" attitude. Watch it here, it does really try to use the best fitting word under the circumstances. Even in their slogan to drive the message through it starts with "words are powerful, use them thoroughly/carefully/well". We do live though in a world which is a tad lopsided. When sometimes the use of the correct word can land one in hot water.
