At last, someone has written about Wordle!

I've held off on blogging about Wordle, because everyone else did it, and because I didn't have anything particular to say. People tend to assume that if you're a linguist, you like word games, but I don't think that's any more true for us than for normal people. Some of us do, others don't. I happen to love crosswords (because there is a quiz or a puzzle element) and dislike Scrabble (because I'm not good at anagrams). I do, as it happens, love Wordle. I love logic puzzles like sudoku, and this is basically just a logic puzzle with an added constraint. 

There is, or used to be, a board game called Mastermind which was a pure logic version of Wordle. (If you don't know what Wordle is, by the way, I don't know where you've been. It's what we all spent the early part of 2022 doing.) There, the thing you had to guess was the sequence of coloured pegs. There were only a few colours, and only a sequence of four, so much fewer than the 26 letters and five slots that Wordle involves. And you needed like ten goes to get it, rather than the six that you get with Wordle. The rules were the same: you got told if you'd got one right and in the right place, or right but in the wrong place, or wrong. You weren't told which one, though, which did make it harder in that respect (otherwise it would have been incredibly easy). I loved this game and I'm not sure why I never had my own copy (maybe no one else liked playing it with me, or maybe I never mentioned that I liked it?) but I played it when I was at other people's houses. 

So yes, I do love Wordle, because of the logic puzzle aspect. The word part of it does add something interesting for me, though. I like the constraint it puts on the possible answers. It's not the case, as in Mastermind, that every combination is equally possible. Some just aren't, or are much less likely, and that's due to the rules of either languages in general, or English in particular. So an example of a language-in-general thing is that there are going to be some vowels in the word, and some consonants. An example of an English-in-particular thing is that the last letter is probably an 'e' or a consonant, because we don't have so many words that end in 'a', 'i', 'o' or 'u' (though we do have some, so it's not absolutely ruled out). Another English-in-particular thing is that if you know you've got an 'h' in there somewhere, it's possibly the first letter but if it's not, you've likely also got a 't' for 'th' or a 'g' for 'gh' in there. Not always; ahead would have stumped me in that case. 

Screenshot of my Wordle stats showing a normal distribution with most words taking me four guesses to get.

I've been paying attention to how I solve them, and I usually get the answer on the fourth go. I imagine this is true for most people, as we'd expect a 'normal distribution' with very few right on the first or second go (that's a lucky guess) and few taking six (that's some bad luck or a word that has many very similar to it). 

I'm not sharing any new insights on how to solve them – I just do the same as you all do and rule out the most common letters first until I can see what it's likely to be. But what interests me is how quickly you get to the point where it can only realistically be one word. This is normally where I am by guess four. 

Here are a couple of recent ones, where the answers were epoxy and lowly. Just coincidence that they both end in a 'y', I think. I vary my starting words but always try to include some common letters. Sometimes I just use things I see nearby like the dogs' names. In both these cases, by the time I'd had three guesses I didn't have many right, but I had ruled out nearly all the possibilities, and there was only one possible word that I could think of in each case that could fit what I knew. 


Screenshot of Wordle with the word 'lowly', correct on the fourth go with few correct letters on the previous three. The previous image shows the same but for 'epoxy', but I can't edit the alt text for some reason.

This is the most satisfying way of playing the game, I think. If you end up with only one letter to get and several possibilities, it becomes chance and annoying, and if you get it right with some lucky guesses you don't feel like you earnt it, whereas this way you feel happy that you worked it out. 

I also saw Lesley Jeffries talking about doing it in other languages, and noting that her guess distribution was much more spread, presumably because her vocabulary is not a large in those languages and so she is likely to need more goes to get it right than the average speaker of that language would (and she noted that she is relying on phonotactics, which is those rules of the language that I mentioned earlier).

So syllogisms are tricky things

Hooray! It's been too long since Richard Dawkins last tweeted something massively ill-judged for me to blog about.
The context: Dawk is back in a previously-contested argument in which he says that 'mild' rape/paedophilia/violence is not as bad as 'violent' rape/paedophilia/violence, and then the rest of the internet gets cross with him about it. Previously, criticism was mostly around the debatable existence of 'mild rape' or 'mild paedophilia', whereas this time he has been more precise and talked about date rape versus violent rape at knifepoint. We don't need to debate which is worse, or if there is any need to have a hierarchy of such crimes (that's for judges or experts in traumatic incidents to decide, I suppose). What I want to focus on is two vaguely linguisticky things: Dawk's utter failure to grasp the need for something beyond logical truth, and 'so'.

Dawk is presenting this as a logical syllogism (in response to criticism; it wasn't how he first presented it). It isn't actually a classical syllogism, which is the 'all men are mortal' type of deductive reasoning. Really, he's just refuting an implication that some people inferred from a statement of comparison. It's unfortunate that the newspapers that get their content by summarising twitter feeds (I'm looking at you, Independent) couldn't be bothered to find this out, but no matter. While syllogisms and other logical arguments are relevant to linguistics (and I have fun teaching them in my semantics module), more important here is the fact that Dawkins is just banging on and on about logical truth, never seeing that the logical truth of his statement really isn't the point. Nobody seems to have put this in a way that he can understand, so it's not entirely his fault, but still: rape, paedophilia and the like are highly emotive topics and there is currently a lot of discussion about 'rape culture'. Given this, it's not surprising that many people would be less concerned with logical truth and more with the rhetorical effect of such public statements. Many people are extremely worried that some instances of rape are trivialised or simply discounted because the victim was drunk/married to the rapist/didn't say no etc. Saying that date rape is less bad than violent knifepoint rape may be logically true (or it may not be - Dawkins is agnostic on the matter), but humans do a lot more than just compute logical truths. We actually have to work quite hard to see purely logical truth (hence the zillions of logical fallacies that we can make), and we set a lot of store in the inferences we make. Even though saying that X is not as bad as Y doesn't condone X, it still appears to make excuses for those people who dismiss the 'date rape' cases as 'not really rape'.

So, on to 'so'. In the tweet pictured above, someone passive-aggressively tweets about Dawkins, not to him, while @ing him so that he sees it. This is the height of bad twitter manners. Dawkins, in his response, takes exception to Sequester Zone's use of 'so', asking why they used it. I assume that Dawkins is making bizarre linguistic assumptions again, and would hazard a guess that he considers 'so' to be incorrect when it is used as an introductory particle, similarly to 'and' or 'but'. I've seen some other peeving about this lately, with people claiming that 'everyone is starting their sentences with so these days'. As it happens, I agree with much of what it says in the article linked via the response above, but 'so' doesn't always indicate a rehearsed pitch or dumbing-down. It's long been used as a turn-beginning marker, or as a way to indicate that you're returning to a previous topic, or many other things. The OED's got an example from 1602 in their sense 5c, where it's a kind of 'hey I'm talking' marker:
So, let me see, my apron.
And in sense 10b(a) from 1710 (Swift, no less), where there is no preceding statement but one is implied:
So you have got into Presto's lodgings; very fine, truly!
And 10b(b), which it attributes to 'reflecting Yiddish idioms', where there is no preceding statement, or where there is adversative force (probably the use in the tweet) from the 1950s (this example is 1960):
‘I warn you..I ain't got no wine.’ ‘So who wants wine?’
Note, though, that it serves another function within twitter. In a tweet, if you begin with an @-name, it will only be seen by people that follow both parties. The convention, therefore, if your tweet begins with a name but is a mention rather than directed at that person, is to begin with a full stop so that all your followers will see it. Alternatively, you could make sure that the @-name isn't at the beginning of the tweet by using an introductory particle such as 'so'.

'All the protagonists'?

When I was young I liked to learn facts about language. I was also a smug little git so what I liked best of all was to learn a fact that would allow me to say to people 'You're using that word wrongly'.

I'm still a smug little git but now I know that this is prescriptivism and a Bad Thing. Linguists try to avoid it, and instead describe language usage As She Really Is. For this reason, I've decided to revisit a prescriptive usage that I remember learning as a small child. This was an extra-special one for me, because it involved knowing the  etymology of a word and applying it to modern usage, and this is always a good way to make people feel stupid. (What, you don't know classical Greek? You utter ignoramus.) Yeah, I was insufferable.

Word puzzle

Here's a puzzle that's on the Crystal Maze iphone app (I don't have the app, I'm not recommending it, just stole this puzzle which is on the review page):
Mary is 24. Mary is twice as old as Ann was when Mary was the age Ann is now. How old is Ann?
Answer after the break.
