Different from/to

[Theodora]

I am reading a children's book and found a grammatical error where the author writes '...different to...' To amuse myself I emailed the publisher and let them know so they could correct future copies. I received this reply:

"With regard to the grammatical error you've spotted, this is actually down to author style; the writing is very modern as it is such an action-packed series and aimed at an international market. In fact, you are likely to come across a few more instances of non-standard grammar! I do hope this doesn't hamper your or your children's enjoyment of the novels - they are incredibly popular!"

Any ideas how I should reply (given that 'different to' is just plainly wrong!) or should I just let it go?
Thank you.

It is certainly one that I use to short to sheep from the goats. It is always different from. Drum that into all children.

This is one of my pet hates - I fear that I have several - but seems to be an increasingly common error. You hear it frequently from BBC presenters and announcers as well as representatives of teaching unions and others who really ought to know better. I suspect that some of those who reply to these threads reminding the real pedants amongst us that language is living will say that this is another example of its continuing development. However I still find "different to" grates on my ear.

"Different to" grates on my ear too though I guess its use is so common that maybe it's now considered acceptable. What is even worse is "different than".

You might list ways in which Tesco "differs from" Sainsburys but never ways in which it "differs to" Sainsburys.
