Language death is like no other form of disappearance. When people die, they leave signs of their presence in the world, in the form of their dwelling places, burial mounds, and artefacts - in a word, their archaeology. But spoken language leaves no archaeology. When a language dies, which has never been recorded, it is as if it has never been.

The Internet has given us 10 or 15 new styles of communication: long messages like blogging, and then short messages like texting and tweeting. I see it all as part of an expanding array of linguistic possibilities.

Likewise, there is no evidence that texting teaches people to spell badly: rather, research shows that those kids who text frequently are more likely to be the most literate and the best spellers, because you have to know how to manipulate language.

English has been this vacuum cleaner of a language, because of its history meeting up with the Romans and then the Danes, the Vikings and then the French and then the Renaissance with all the Latin and Greek and Hebrew in the background.
