great blog idea! we have been informally following britishisms for severals yrs.!
I first saw “bespoke” used in a sartorial sense in an article about evening wear, during last year’s run-up to the royal wedding. And, when one looks up the definition, that’s the first, and often the only, meaning that pops up.
Whatever happened to the meaning for which I’ve always used the term, i.e., as the past tense of “bespeak”? One must dig deep to find that meaning even mentioned.
Bespoke has re-entered current usage because of the increase in custom made kitchens, as oppose to the ones you put together yourself from standardised units from, say, IKEA. In the UK, kitchen units in standard widths and different finishes, can also be bought from the ‘sheds’. This is the slang for our equivalent of Home Depot.(I think!). Bespoke kitchens are what we all would like could we afford them. British homes are usually smaller than you might be used to, pokey really, and bespoke means you can make us of every last bit of space.
