The growing Americanisation of our language seems to have accelerated massively over the last few years. I see 'mom' scrawled with abandon all over Mumsnet. Schoolchildren regularly refer to 'math'.
Yes, what happened on Sept 11 2001 was utterly tragic, and I am not seeking to cause anyone pain, but for some reason the totally illogical American date format really annoys me, even more than seeing a fine word lose its 'u'. Month/Day/Year - how can that possibly make any type of sense????
It's now long enough ago that when I talk about it to others, it causes them to stop for a moment and think - and thinking consciously about the loss of British English is maybe the first step to preserving it.
