Getting back to Kelley of Delaware's queries (which I started answering
here):
Every weekend this time of year there are dozens of yard/garage sales in my town. Do such things exist in the rest of the English-speaking world, and, if so, what are they called?
I can't speak for the rest of the English-speaking world, but similar things do exist (to some degree) in England, though not by the names
yard sale or
garage sale. These things are allegedly named after the locations in which they occur, however the ones I've passed by this week (in NY state) that have been advertised as 'yard sales' or 'garage sales' were mostly actually in (chiefly
AmE)
driveways (
BrE drives) next to (
AmE)
yards or garages.
AmE has other terms for such kinds of sales, including
tag sale (popular in New England). Many of these terms can be seen at the Dialect Survey map
here.
(Side note: The pronunciation of
garage was a point of discussion at dinner tonight. Better Half's
mum said it in her normal way, so that it rhymed with
HAIR ridge carriage, and my
mom expressed her admiration of
BHM's unfamiliar pronunciation.
BHM countered that the
AmE (and sometimes preferred
BrE) pronunciation gər-
RAZH was nicer.
Garage is one of the few words (maybe the only word?) that
BrE speakers have complimented my (
AmE) pronunciation of. This is
another case in which the
AmE pronunciation is closer to the original [French] pronunciation than the
BrE--which only matters if you're one of those people who think 'older' means 'better'.)
Of course, part of the reason that people don't have yard sales in Britain is that they would not call the
un-built-upon fronts of their properties
yards. That would instead be the
front garden (at least, if it's planted). (This was a point of contention between an American and an English friend this summer. The American kept calling the Englishwoman's garden a
yard, and the Englishwoman kept letting the American know that she felt insulted by this description.) Nevertheless, there is nothing called a
front garden sale either. I've not seen many sales of household merchandise on/in residential properties in the UK, but those that I have seen have been advertised as
moving sales. Obviously, that term only applies to certain situations, when people are trying to get rid of things that they don't want to cart to their new abode. There may be a term for non-moving household sales that I've not come across. (Answers in the comments, please!) But these kinds of things are pretty rare--at least in my neck of the English woods.
What the UK does have (and the US generally doesn't) are
car boot sales. These take place in public spaces, usually a (
BrE)
car park/(
AmE)
parking lot [or a field--see comments]. People put the things that they want to sell into their car's (
BrE)
boot/(
AmE)
trunk, then set up a little stall of their wares (often using a folding table, etc.) by their car in the car park/parking lot (typically paying a fee to the
organi{s/z}er/landowner). These happen all year round--there is one that happens every week, for example, at Brighton station. Big ones like that often have professional sellers, who may be selling new or used goods (so they resemble flea markets). Others, like the one at a school near our house, are more geared toward(s) the occasional seller.
Both countries have other types of sales in which people donate their used goods for a one-off sale (and possibly social event) to benefit a charity--for example a church. In the greater part of the US, these are called
rummage sales, although they may have other regional names. In the UK, they are
jumble sales.
White elephant sale is a term that I heard as a child in the US (and it was already old-fashioned at that time), but that I've seen more often in the UK.
When I asked Better Half if he knew of any
BrE equivalent of
yard sale, he drew a blank and noted that such things are a rarity in Britain. One reason for this is that most British homeowners wouldn't have the space for such things. Front gardens/yards tend to be very small, drive(way)s are quite short, and garages are a luxury in town cent{er/re}s. Another reason is that most British homeowners just don't have the space to store as much unwanted junk for as long as American homeowners can--and thus they can't store up a sale's worth of merchandise.
BH's mum, for example, has a good-sized three-bedroom house. But as is typical of a post-war London home, she has no basement, no attic to speak of, no garage, and no walk-in closets. In that situation, one doesn't wait long to get rid of clothes that don't fit, gifts that didn't hit the mark, and decorations that have been replaced. People have various ways to get rid of unwanted stuff (and, it must be said, they tend to buy less junk in the first place), with
charity shops (AmE: thrift stores) playing a major part in the second-hand economy.
