I've said it before; grammar is quite important.
I spent the weekend snowboarding up in the mountains. On Saturday evening whilst I lay sprawled on the armchair feeling particularly exhausted, an ad on the local TV station used the word "moister".
This was used to indicate that the thing being advertised was more moist, or contained more moisture than some other thing.
What a horrible use of English. It seems the people writing the copy for the ad were of the impression that grammar is the lady their grandpa married.
I don't know how this happens as you'd think there would be someone involved in producing this abomination of an ad that would flag the use of the word "moister" as being unacceptable.
And so it was that Saturday was the day 'moister' became my new most abhorred word. If only I could remember what product it was used in relation to, I could advise everyone against buying it.
