These two words strike me as profoundly useful, and not only as fodder for Call My Bluff. English, as the distinguished lexicographer Sarah Palin reminded us last month after coining the verb "refudiate" as an alternative to "refute", is a "living language. Got to celebrate it!" Dr Johnson and H W Fowler, gods to word-nerds both, may have been able to get by without a term to denote the waxy coating that is scratched off an instant lottery ticket, but I'm not sure that citizens of the 21st century are.
