In 2009, my parents came over from the US and we took a trip to Italy: Florence, Pisa, and Rome. The food, of course, was gorgeous, but often clashed with what my mother thought of as "Italian" food—the type that one gets in the northeastern US, where Italian immigrants brought over a lot of southern Italian dishes, which were then adapted as tastes and ingredients changed. Because of this, she repeatedly asked "Is it in a red sauce?" Many of the waiters found this a strange question, but they could deal with strange questions from paying foreigners. My British spouse, however, found it too annoying: "What do you MEAN?" And Mom would say "You know, a red sauce. Like [AmE] spaghetti sauce". But he didn't necessarily know, because naming sauces by colo(u)r seems to be a peculiarly monocultural thing. 

red sauce

Red sauce was only added to the Oxford English Dictionary (OED) in 2005, so its definition is pretty up-to-date and shows the American sense:

(a) n. Any of various sauces that are red in colour, esp. (in the United States) a tomato-based sauce of southern Italian origin; (b) adj. (attributive) U.S. of or designating a type of Italian American cuisine characterized by the use of tomato-based sauces.

Wikipedia tells us:

Red sauce may refer to:

That list demands a translation and a synonym. Marinara sauce in AmE refers to a rather plain tomato sauce for pasta—the default pasta sauce in the US. It is so-called because it was reputedly the kind of simple sauce made or eaten by Neapolitan sailors. In the UK, one sees the word marinara on Italian menus referring to seafood sauces.

An Australian ketchup

An American passata

As far as red sauce referring to ketchup in the UK, I have heard it, but not often. Ketchup is the most common word for it in both countries, though Britons are six times more likely than Americans to call it by the full tomato ketchup (six times more likely in the 2012–13 GloWbE corpus, eight times more likely in the more recent NOW corpus). You sometimes hear in BrE the more AusE tomato sauce. In AmE, that doesn't mean 'ketchup', but is the equivalent (more or less: see comments) of the stuff that in BrE is usually called passata.

brown sauce

The British have brown sauce, of which HP Sauce is the original and most famous example. It's a condiment one buys in a bottle, made with vinegar, fruits, and some form of sugar. It is most often used with breakfast, and we've seen it before in my opus about bacon sandwiches.

Wikipedia's photo at brown sauce

a tangy sauce commonly served as a condiment for beef in the United States. Two of its major producers are British companies

That last bit was news to me. I import A.1. from the States because I love it so. (I find it spicier and less treacly than HP sauce. It's also much darker.) In the UK, I've only ever seen it in Fortnum and Mason (extremely chichi shop), where they charged in the double digits for a bottle, apparently imported from the US. But A.1. (in some formulation) may still be being made in the UK for export to Asia! (The most recent reference to this I've found is 2018.)

Back to brown sauce. The OED definition has not been updated since 1888, and it has only the French-cuisine inspired meaning, akin to gravy: "A brown-coloured savoury sauce, esp. one made with browned fat and flour." When I was a(n American) child in the 1970s–80s learning about cooking, I learned this among other sauce terms—though I can't say I've ever heard it in my adult life. 

But brown sauce was another bit of my mother's terminology that didn't help when travel(l)ing: she'd talk about her Chinese food preferences in terms of preferring brown sauce over white sauce, and British Spouse didn't understand what she meant. But, she knew what she was talking about. Goodcooking.com has a story about a sauce master at a Chinese restaurant which includes (with recipes): 

Two basic sauces are the brown sauce and white sauce. Brown sauce is mainly for meat dishes; beef, lamb, duck, yet he also used it in his Chendu Fish dish, to bind together moo shu and one of his tofu dishes. The white sauce was for fish and seafood, chicken and vegetable dishes. Other ingredients such as black beans, chili with garlic, preserved vegetable, ginger and garlic were added as items cooked and then his sauces were added, seconds before service to bind everything into a flavorful dish. 

From the spelling of flavorful, we can guess that this Chinese restaurant was in the US, and from a little knowledge of Chinese food in the anglosphere, I would guess that (a) this might be based in some specific regional Chinese cuisine, and (b) the term is not much used in British Chinese cuisine. Having had a lot of Chinese takeaways/takeout in the US, UK and South Africa, I can report that even if you're ordering a dish of the same name (chicken in garlic sauce, sweet-and-sour pork, General Tso's chicken etc.), they are very different in different places. (Let's just say: my English family always makes a point of having Chinese food when we're in the US.) Yummly.co.uk has many recipes for Chinese brown sauce, but, despite the 'uk' in its URL, all the brown-sauce recipes I checked there have American terminology (cornstarch, scallions, chicken broth/bouillon etc.). If there were any urge to call Chinese sauce base brown in British English, it would probaby be blocked by the clash with the breakfasty condiment. 

white sauce

White sauce has at least the following meanings: 

• In (US, at least) Chinese cuisine, it's the opposite of brown sauce. (This site says it's typical of Cantonese cooking.)
• A sauce base made of "roux of butter and flour combined with milk or cream" (OED). 

The OED's (2015 updated) entry includes only the last of these, which is often used in French cooking. It's also what my mother used as the opposite of red sauce in Italian cooking, so an Alfredo or similar. 

Speaking of white sauces in Italian cooking—I grew up hating (AmE) lasagna/(BrE) lasagne because I couldn't stand the ricotta cheese. Well, it turns out, British people don't make lasagne with ricotta (nor do many in Italy). Instead it has a béchamel sauce. Meanwhile, I've outgrown my hatred of ricotta. Still, lasagn{a/e} is the last thing I'd order on any pasta menu.

Finally,

for the fun of it, a Venn diagram of sauces by Zoe Laughlin,  recently discussed on BBC Radio 4 and pointed out to me by one of my writing group pals:

At the Bavard Bar in St Leonard's a few months ago, a Bavardier asked me if I'd noticed the difference between the US and UK meanings of second-guess. I hadn't! She felt that the US meaning was overtaking the UK meaning, but whose meaning is really whose? 

Here's what Oxford Languages says: 

It looks like only the first of those meanings ('anticipate by guesswork') initially went to the UK, while that meaning perhaps lost steam in the US. The American Merriam-Webster dictionary lists the 'criticize' meaning first. 

For me, 'judge with hindsight' doesn't capture how I use second-guess. Here's me using it in The Prodigal Tongue, talking about the acts of faith we need to take in communicating:

when you’re talking with people from other places, you cannot second-guess every noun and verb you utter.

If we use a substitution test to see which of the definitions above fits with it, it's not very satisfying. 

1. you cannot anticipate every noun and verb you utter. 
2. you cannot judge with hindsight every noun and verb you utter

Neither seems to me to capture what I meant, which was something more like:

• you cannot spend time doubting and re-thinking every noun and verb you utter

This sense of 'doubt' seems to come through when second-guess is used with a reflexive (-self) pronoun, as in I spend too much time second-guessing myself and, it turns out, there are about 2.5 times more second-guessing of oneself in the American part of GloWbE corpus as in the British part:

Wiktionary's definition might be more in line with my intuitions of the meaning. 

1. (idiomatic) to vet or evaluate; to criticize or correct, often by hindsight, by presuming to have a better idea, method, etc. quotations ▼

   Please don't try to second-guess the procedure that we have already refined and adopted.

   Once she began listening to her instincts and didn't second-guess herself the entire time, her artwork improved noticeably.

Their use of the originally BrE verb to vet seems to capture what I meant in my sentence: 'One cannot vet every noun or verb for its dialect-appropriateness before it comes out of one's mouth.'  I'm betting this usage has arisen by 'contamination' from a similar, but centuries-older phrase: have second thoughts about.

That's not to say I always use it in the 'vetting' way. Here's an example from an email I sent, replying to a question of whether students would like to join the staff in a reading group:

I don't think we should second-guess whether students would want to do it; I think we should just invite them.  

This one has more the 'anticipate' sense. I don't think I picked that up in the UK. Rather, I think the phrase does more than one thing for AmE speakers. 

So, is my fellow Bavardier right that things are changing in the UK?  Let's look in the News on the Web corpus, since that covers the past 14 years, whereas the GloWbE data were from 2012.  Using the same search string as I used in GloWbE (second-guess* *self), there is still 2.5 times more in the US subcorpus than in the British subcorpus. If we just search for second-guess* (without the *self), it's 2.2 times more in the US. 

But we can see it really picking up in BrE since 2017:

So it feels kind of 'new' in BrE. But while it's older in AmE, there's certainly a great increase in its use in the past few years. Perhaps it's that increase in the US that's allowed it to be picked up in the UK:

Rather than me second-guessing your thoughts on this, why don't you just tell us in the comments?

See here for the UK-to-US WotY post.

Time for the 2023 US-to-UK Word of the Year. Before people complain that this word has been in British English too long for it to count as a word of 2023, let me remind you of the criteria for SbaCL WotYs: 

• Good candidates for SbaCL WotY are expressions that have lived a good life on one side of the Atlantic but for some reason have made a splash on the other side of the Atlantic this year. 
• Words coined this year are not really in the running. If they moved from one place to another that quickly, then it's hard to say that they're really "Americanisms" or "Britishisms". They're probably just "internetisms". The one situation in which I could see a newly minted word working as a transatlantic WotY would be if the word/expression referenced something very American/British but was nevertheless taken on in the other country.
• When I say word of the year, I more technically mean lexical item of the year, which is to say, there can be spaces in nominations. 

OK!

Dailymail.co.uk headline. Not linking to them because they don't need the traffic

[I]n American English, right conveys the speaker's knowing stance and, in certain environments, the speaker's claim of primary knowledge. In contrast, in British English, right registers provided information as previously unknown, informative, and relevant to the current speaker's ongoing project. 

        [...] 

[S]ome UK usages of right—such as registering of potentially consequential information and projecting a transition—are quite similar to US okay in comparable positions [...]. This suggests a possibility that, in US English, okay took over some of the right usages and/or, in UK English, right took over some of the okay usages."

Their research was inspired by this interaction between BrE-speaking "AB" and AmE speaker "GA":

So, essentially, the British use of right in that context leads GA to think that AB is confirming (rather than acknowledging receipt of) the information. If AB had said OK, then GA would have understood it as acknowledgement rather than confirmation.

Even though the researchers note differences in usage between BrE and AmE okay (though keep in mind that their research is about right), it seems like a fitting US-to-UK WotY because (in whichever usages), it's used more than ever in the UK. Here it is in the British section of the News on the Web corpus, where it shows OK and okay climbing in the last couple of years.

Each year since 2006, this blog has designated Transatlantic Words of the Year (WotY). The twist is that I choose the most 'of the year' borrowings from US-to-UK and from UK-to-US.  The question this year raises is: does 2023 deserve SbaCL Words of the Year?

The eligibility criteria remain:

• Good candidates for SbaCL WotY are expressions that have lived a good life on one side of the Atlantic but for some reason have made a splash on the other side of the Atlantic this year. 
• Words coined this year are not really in the running. If they moved from one place to another that quickly, then it's hard to say that they're really "Americanisms" or "Britishisms". They're probably just "internetisms". The one situation in which I could see a newly minted word working as a transatlantic WotY would be if the word/expression referenced something very American/British but was nevertheless taken on in the other country.
• When I say word of the year, I more technically mean lexical item of the year, which is to say, there can be spaces in nominations. Past space-ful WotYs have included gap year, Black Friday, and go missing. I've also been known to declare a pronunciation the Word of the Year.

And here it is in British sources in the News on the Web Corpus: 

In the 2012 data, the phrase occurs at a much higher rate in GloWbE than in NOW—the NOW number only reaches GloWbE's rate (1.8 per million words) in 2023—because the types of texts in the two corpora are different—there's more variety and informal language on GloWbE. That's something worth keeping in mind when we look at the US numbers. Speaking of which, here they are:

A few things to notice here:

• Yes, the phrase is going up in AmE news, from 0.08 per million words to 0.19 over the past 13 years. 
• But it's still below the 2012 GloWbe number (0.24 pmw). One would imagine that if we had current data that was collected in the same way as GloWbE, we'd see a lot more there. 
• And it's wayyyyyy below the British numbers.
• A country music album had the title If I'm Honest in 2016, which helps (to) account for the higher number then.

Here's a view of the Google Books numbers, comparing If I'm honest with To be honest (though keep in mind that to be honest here is not necessarily the discourse marker. It could be in any number of sentences about honesty.)

And a comparison of it with the equivalent if I'm being honest, which is less common, but making a move in AmE.

The pictures (and numbers) tell the story of a British expression that's become more and more common in BrE, and that has raised American exposure to (and use of) it. But note that it's rising far faster in BrE than in AmE. So, does it meet the first of my eligibility criteria? Maybe not. But it's what I've got for this year!

P.S.  Honestly

Honestly, used as a discourse marker in a sentence seems to be more common in AmE. But as a stand-alone expression of exasperation, it seems more common in BrE (Honestly!). It's definitely more common from the BrE speakers in my house than from me, but maybe I'm just more exasperating to live with than they are. Here are searches with punctuation from GloWbE:

Will there be a US-to-UK WotY?  To be honest, it's unclear at this point! 

Smylers got in touch recently with this observation:

I found myself being surprised by the word “mobility”, and was wondering if there's a BrE/AmE difference? Enterprise Rent-a-Car emailed to say they're introducing a new brand: Enterprise Mobility. 

That made me think of vehicles adapted for wheelchair users, or those who otherwise have limited personal mobility. But apparently it's the overall brand for various transport services; “mobility” is being used to mean “travelling in a vehicle”, rather than “travelling on foot”.

There's no reason why the unqualified word should have one or the other meaning. But to my British brain, “mobility” makes me think of “mobility scooters” or “mobility aids” — such as those provided by Mobility People, whom you linked to in 2008:

It's an interesting one. 

The word mobility seems a bit more common in BrE in the the News on the Web corpus: you find about 11 mobility per million words in the US, versus about 13 per million in the UK. Those British uses tend to relate to a couple of domains: physical (dis)ability and social class.

It's not that Americans don't use mobility in that way. You can definitely find phrases like mobility scooter (as can be seen at this US electric wheelchair retailer) in AmE. (Though when I asked my brother what those things are called, he didn't use the word mobility, just scooter.) Nevertheless, this (dis)ability-related use of mobility used a lot more in BrE:

The (dis)ability-related uses of mobility really take off in this corpus after 2021. For instance, mobility issues (which could refer to different kinds of mobility, but mostly doesn't) had only 0.30 per million (across countries) in 2019, but 0.85 per million in 2022. 

Both AmE and BrE use mobility for metaphorical movement, as in social mobility. 

mobility + noun

Noun + mobility

Adjective + mobility

Having spent so many years on Twitter doing "Differences of the Day",  I have a lot of (forgive me the jargon) content that could be moved over here, to the blog. Today, I'm moving over the information from tweets that I did during my "fire week" in March 2018: five days of AmE–BrE differences relating to fire-fighting. This choice has been inspired by Frank Abate, an American lexicographer who regularly sends me the BrEisms he's come across in reading the news.  So, this post is mostly copy-pasted-edited from tweets—the smaller text is info I've added since the tweets.

Ways of referring to people who fight fires as a job:

• AmE and BrE both use fireman and firewoman (though News on the Web corpus has both of these at higher rates in UK now)
• orig. AmE fire fighter (or firefighter) is used about twice as much in US
• BrE fire crew and fire (safety) officer (which is a higher rank) are not much used in US.

(Fire) appliance is much more common in news/officialese in BrE than AmE (and get a look at NZ!). This goes back to mid-1800s, and refers to a fire engine (used in both countries). AmE has fire truck, but that's a more informal term than engine/appliance.

Fire appliance in the News on the Web corpus.

That reminded me of a sign on the fire station near my house in Brighton:

Finally, fire hydrant was originally an Americanism, but is now used in the UK too. They look rather different, though.

UK hydrants are marked by yellow signs with an H, which tell firefighters that there's access to a pipe nearby. I wish I could remember what I watched on television last week that had an American hydrant in an allegedly UK setting. It's one of those things that will really stand out to those who know. Two points to any commenter who can name the show or film!
