Traditional. A word as vague as it is handy. It covers any period more than 20 years in the past. Or earlier than you can remember. About as precise as that. Don't know any exact dates? Just use "traditional" instead.
Now I've realised that, every time I see the word it jumps off the page (or the screen). That gives me an idea, why don't I post the most flagrant and gratuitous uses of the word "traditional"? I could make it a regular feature of the blog.
Before you ask, this isn't an innovation. Private Eye have been doing something similar for years.
For no particular reason other than I just stumbled across them, here's a couple of outstanding examples of how to obscure history by the use of "traditionally" from Charlie Papazian:
"Contrary to popular belief the original Guinness draft stout is not strong ale; it’s no more than about 3.8% alcohol, even today. The bottled stout labeled “foreign export” traditionally reaches up to about 6% alcohol."
"Stout’s deep brown/black color suggests strength, yet traditionally this beer was brewed to lower strengths. Even today, draft stouts in Ireland are at about 3% alcohol."
Random. Totally random.
