Good point Genie. I do have my pet hates with 'mistakes' in grammar and spelling as I learned them. Pronunciation too. However,I think it's like tilting at windmills to turn back the tide of language change (if I can mix metaphors.

For what it's worth my pet hates are cervical with a long 'i', dissect with a long 'i', aitch pronounced as if it started with an 'h', clumsy constructions to avoid splitting infinitives (a meaningless construct in English), your example of 'Tom or I' above.

On a parallel thread someone was writing about ITA which failed mostly I think by stopping children writing the same language as their parents and grandparents
