Often I challenge you to use my Wednesday Word of the Week, but not this time. I'd like this one to vanish.
Invent is a word. It means to use thought to create and originate. The result is an invention, created by an inventive inventor. It could be a physical thing, such as a wheel, space ship or cake. It might be an idea, song or story.
Re-invent doesn't mean anything, or at least not anything good as far as I can tell. Re-inventing usually seems to involve taking something good and popular and messing it up. Favourite food products are re-invented with a 'new and improved' recipe meaning they're smaller, pricier and disgusting. Classic stories are re-invented as unconvincing, watered down versions of the original. Re-invention is so much not a thing, that I'm not even going to make the letters bold.
Ooops, Wednesday Word of the Week seems to have been re-invented as Wednesday Whinge of the Week! I'm right though ... aren't I?
