Extract from Times Feedback today, a column which often fields pedantic complaints from readers:
'...whether we had been catering to a rather restricted audience...'
I've mentioned 'catering to' here before (surely 'catering for'?). It's also a favourite of the paper's bridge correspondent, Andrew Robson, (e.g...'cashed the ace, catering to West having a singleton king...').
However, the column does lead with the Apostrophe Protection Society, which I am glad to see has been revived.
Re PH: yes there are bound to be spelling and pronunciation pitfalls. Another one is ophthalmologist with its apparent link to the 'aitchless' optician.
That reminds me of another cringe, the often heard h as in haitch*.
