One of the interesting things about idiomatic expressions in any languages is that, while the words in them may each make complete sense, stringing them all together may seem to make no sense, at least to someone who isn’t a native speaker or, if they do make sense, the literal meaning is far different than the idiomatic meaning.
A good example of the latter in English is the expression “a piece of cake.” Literally, it’s just a bit of dessert. Nothing odd about that. But, of course, English speakers know the other meaning. A “piece of cake” is something that is done or achieved very easily: “Passing that test was a piece of cake.” Why does a fluffy, iced treat mean this? Who knows.
By the way, the Spanish equivalent of the expression is “pan comido,” which literally means “eaten bread.” Again, it’s a food metaphor, but why it would indicate that something is easy is still a mystery. Maybe, because after you’ve eaten that bread, no one can take it back? So maybe it makes an ounce more sense than its English counterpart. Maybe not.
When it comes to all the words together making no sense, though, we come to an English expression like “cold turkey.” If you didn’t know what it meant, you might assume it refers to a really lousy Thanksgiving dinner. However, what it really refers to is quitting a habit instantly — for example, quitting smoking by just stopping. And yes, the habit is usually something addictive, like smoking, drugs, or alcohol. There’s no clear source for the phrase, although it may have come from come from an alteration of the phrase “to talk turkey,” meaning to speak honestly and plainly, modified with “cold” as in “cold, hard facts” — to deliver something without emotion.
Another fun expression that is more British than American English is “taking the piss,” a short version of “taking the piss out of.” You could be forgiven if you thought this referred to urologist’s daily routine, and don’t confuse it with “taking a piss,” which is somehow both literal and backwards at the same time. I mean, really — doesn’t one “leave a piss” rather than take it?
This expression has nothing at all to do with urine. Rather, it means basically mocking someone or joking at their expense, although how this came to mean that is still unclear. It may have come from Cockney rhyming slang, and the fact that it’s popular in Australia, New Zealand, South Africa, and Ireland, but not in Canada attest to this, although one really wild and unfounded theory refers to the use of urine to tan leather — take this one with a big fat grain of salt. One other possible etymology links it in to another slang term, piss proud, which relates to that quaint phenomenon most men are familiar with called morning wood.
Now back to the top and an interesting idiomatic expression from Spanish in which each word makes sense but all of them together don’t add up to the idiomatic meaning: de par en par. Literally, it’s “of pair in pair.” I’ll give you a moment to take a wild guess as to its actual meaning.
This paragraph provided as a think break before the spoiler. Here’s a really weird idiomatic expression from Swedish: “Att glida in på en räkmacka.” Literally, it means to slide in on a shrimp sandwich. What it really refers to is somebody who didn’t have to work to get to where they are. An American version might be “born on third base” or “born with a silver spoon in their mouth.” Okay, enough of a break. Any ideas on what “de par en par” means?
Okay, here we go. For some reason that I haven’t yet been able to determine, it means “wide open.” And you can put all kinds of open things in front of it: “una puerta de par en par,” a wide open door; “con brazos de par en par,” with open arms; “un corazón de par en par,” an open heart, and so on. (Interestingly, negating the expression by changing it to “sin par en par” does not mean “shut.” Rather, it means unparalleled. Weird, eh?)
If anybody does happen to know why this expression means what it does, please share in the comments. For that matter, if you know the whys of any of the English slang phrases I’ve mentioned, do likewise.
