Anyone into cryptic crosswords will know most cryptic clues are trying to say two things at once. Take a clue like Friendly astronaut's beginning to probe alien planets (9). If we "translate" its indicator words and capitalise the fodder to more clearly show that they're just strings of letters, we see that the clue's real meaning is something like ASTRONAUT's beginning first letter to probe go into alien anagrammed PLANETS.
To grasp that cryptic reading, we have to ignore the misleading story the surface is pushing on us, and we have to give new or quirky meanings to individual words in the clue, but we don't really have to modify the grammar. In the reformatted version of the clue, the ordering of the words and the relationship between them is familiar from how English is used in real life. That word order is of course part of the meaning of the clue (to take the most obvious example, it tells us that the letter A goes into the anagram, not the other way round).
What if the clue had used "head astronaut" to indicate the A? Translating that would have given us "first letter ASTRONAUT", and we'd have needed to apply a further translation to get back to something like "first letter of ASTRONAUT" or "ASTRONAUT's first letter". For many, that sort of thing means the clue's cryptic grammar is imperfect, not so much because it's broken a rule, but because it doesn't resemble the normal patterns of English. Cryptic grammar is the idea that the grammar underpinning cryptic clues should not in itself be a puzzle β that's the job of the surface and the meanings of the individual words that make up the clue.
The usual argument for paying attention to cryptic grammar is that it's fairer for the solver if they can rely on ordinary grammar and without having to guess their way towards newly invented grammatical rules like "head astronaut" can mean "head of astronaut". It's true that leaving ordinary grammar behind often leads to clues that feel more like vague guessing games than precise instructions, but itβs also true that many solvers will see no difference between "astronaut's head" and "head astronaut". It's a bit silly to suggest that looser cryptic grammar "doesn't work", as if a law of physics has been broken. Looser cryptic grammar clearly can do the job of facilitating a light-hearted word game, though there are good reasons some prefer a more rigid style.
A better argument in favour of cryptic grammar is an aesthetic one: if a clue can be read in two distinct ways and both of these conform to typical English grammar, then the setter is overcoming quite challenging odds to pull off a sort of linguistic magic trick. The crossword setter Fez has compared this to the optical illusion of a duck that looks like a rabbit (or is it the other way round?).
I just think duck-rabbits are neat, so this page is intended as a practical guide to making them, aimed at people who share this interest. When I say below that particular grammatical patterns don't work, I'm just evaluating them within the constraints of this style. This page isn't a demand that everyone writes their crossword clues like this.
In UK broadsheet newspapers and some other contexts, the vast majority of clues use a recognisable style of cryptic grammar. The style has its origins in an influential book by an early crossword setter named Ximenes, but it also includes certain conventions and rules that evolved after that. People new to crosswords often ask if "the rules" are written down anywhere, and the truth is that many of these rules are sort of passed down without being documented in one place. Even if you read Ximenes' book you'll find some striking differences between what Ximenes said and what today's "Ximeneans" do, so I would guess most setters' grasp of cryptic grammar comes from real-life conversations or discussions on crossword-solving blogs.
This guide aims to clear things up a bit by listing different grammatical combinations of indicator and fodder and saying whether or not they're commonly seen in this shared style, which we could call Standard Cryptic Grammar. In a sense all I'm doing here is documenting or describing conventions which exist in modern UK crosswords, but I also try to explain why some things are do's and some are don't's (I also point out a handful of conventions of Standard Cryptic Grammar which, to me, don't seem to be very well-founded in ordinary grammar).
As I said, this guide is mainly based around considering different grammatical combinations of indicator and fodder (I've previously suggested these could be called fodules, and luckily this has been embraced by crossword setters everywhere).
Finally, here are a few general principles which I think we can observe in Standard Cryptic Grammar. They're all derived from the golden rule that clues should "say what they mean" (this idea was popularised by Afrit, another early crossword setter who influenced Ximenes, and basically means that clues should express their instructions in ways which can be inferred from how ordinary English works):
The conventions around selecting particular letters from a word are slightly different from those around other types of wordplay, so it makes sense to deal with them in their own section.
Nouns like "head", "tail", "heart", "sides" and "guts" can refer to particular parts of words. I think the indicators which work best here are nouns which already refer to particular parts of physical or conceptual objects in the real world.
Patterns like these are totally grammatical ways of referring to particular parts of words, because the possessive apostrophes make clear that the particular head/tail/heart/sides/guts etc we're selecting are the ones which relate or belong to the fodder.
Note that if the indicator is singular like "cat's head", the solver is entitled to assume that they're only being asked to select the first letter from a single word. Equally, a plural indicator like "fluffy dogs' tails" is a clear and precise way to ask solvers to select the tails of multiple words. This sort of precision is a good example of how good cryptic grammar can give the solver information rather than misinformation.
These are all fine too. The prepositions "of", "to" etc do the same job as the possessive apostrophes in the previous section, by making the relationship between the indicator and the fodder clear in a way which is rooted in normal English (think of phrases like "name of school", "lyrics to the anthem", "present for mum", "ideas from scientist" and "characters in book").
We're back with "head astronaut" again. Constructions like this are probably the main source of disagreement in different approaches to cryptic grammar. These would always be avoided by people with a strict approach to cryptic grammar, because in normal speech and writing, "head writer" never means the head of a writer, "heart rate" never means the heart of a rate and so on. In fact, there aren't really any common phrases in English where "[X] [Y]" (with or without a space in the middle) refers to an X belonging to Y, so if you're asking a solver to understand these as letter selection indicators you're asking them to use an invented rule which only exists in crosswords.
Many of my crossword colleagues would also reject these because there's still no apostrophe or preposition, but for me the fact the indicator is now after the fodder makes a big difference. While it's rare for English to refer to an X belonging or pertaining to some particular Y with a phrase like "[X] [Y]", there are countless such phrases in the order "[Y] [X]". For example, "city centre" means the centre of a city, and "London skyline" means the skyline belonging to London, and for me that's close enough.
There is a clear argument against the above, but people often do a bad job of communicating it because they just declare things like "party leader" doesn't mean the leader of "party", so let me quickly share an approach that helped me finally understand this one. Imagine having a conversation that's nothing to do with crosswords, then ask yourself which of the following sentences you might use if discussing a word:
We all know "party leader" is a completely unambiguous term for the leader of a party, but for people who favour this argument, that's sort of irrelevant: the point is that "PARTY leader" is not a phrase you'd use for the first letter of "party" in normal conversation, not because words don't literally have leaders, but because no phrase in the form "[word] [part]" ever sounds natural, even when that part is a totally non-whimsical one like a first letter. "PARTY's leader" and "leader of PARTY" don't have this problem, because they still sound natural.
To sum up, one argument says that if "cat head" can mean the head of a cat then it's not that much of a stretch to treat that phrase as a way of referring to the head of "cat" as well, and another argument says that a small stretch is still a stretch and is therefore best avoided.
Here's another lot where I take a different view from many of my colleagues. There's nothing unusual about using words like "arrowhead" and "pigtail" to refer to parts of an arrow or a pig in ordinary, non-cryptic English, so for me those same words can be interpreted as references to the head of the string of letters "arrow" or the tail of the string of letters "pig". I would draw the line at treating something like "reverend" as a clue for R (the "end" of "rever"), as that's probably just trying too hard.
Interestingly enough this is one where people most people who call themselves Ximeneans are in disagreement with Ximenes himself, who argued that while "redhead" for R is unacceptable because redness doesn't have a head, "masthead" for M is defensible because masts really do have heads (presumably he'd accept "party leader" on the same grounds). I don't think anyone finds this argument very convincing these days, because we all agree that we're talking about the strings "mast" and "red", not actual mastheads or colours. We all agree a word has a head, so the only question is whether "[X]head" is a clear and fair way to refer to that head. Either it is, and any X can slot in there, or it's not, and no X can slot in there.
Nouns like "head" make it pretty clear which part of the fodder is being selected, but adjectives generally have to be used with a noun such as "part", "letter", "character" etc in order to work well.
These all work exactly like "cat's head" etc from the previous section, except instead of nouns like "head" we have phrases like "first bit" made up of an adjective and a noun. As with the previous section, prepositional phrases such as "first bit of cat", "introduction to cat" and "opener for cat" can also be used, and a minority of people will also accept looser, apostrophe-less constructions like "cat first bit" and "serpent last character".
In real life, I can't really say "pass me the big" to refer to a big glass of wine (it has to be "the big glass" or "the big one"). In the same way, many adjectives can't stand alone as ways of referring to particular letters. Some phrases do work, though: ordinals i.e. words which are used to order things numerically ("first", "second", "third" etc) and a few other adjectives relating to order (e.g. "penultimate" or "last"). The key thing is whether these words can work like this in real life: I can say "I choose the first", "he was the third", "the last was the best", but it'd sound odd to say "I choose the central", "he was the outer" and "the internal was the best". Since "cat's first" and "serpent's last" function as nouns (shorthand for "cat's first [letter]", "serpent's last [letter]"), some people will accept these as "cat first" and "serpent last".
As noted, "I choose the central", "he was the outer" and "the internal was best" all sound incomplete, so while some would accept "cat first" or "serpent last", we can't really use that pattern here. Again this is a question of what sounds normal in real life. In real life, you don't typically talk about a part or section of something by positioning an adjective in this way. The oldest member of a family is not "family oldest" etc, the lefthand side of a park is not "park left". Some people might make the argument that "January 1st" means the first of January, so "January first" could mean the first part of the word "January", but that's not very convincing as it relies on taking a very specific usage (which only really applies to dates) and expanding it to things which it wouldn't normally or naturally be used with.
Like "head writer" and "tail bone", these don't work because these phrases wouldn't work like this in real life. "First cousin" would never mean the first piece of a cousin, "middleman" would never mean the middle part of a man, etc. I think things get even more unconvincing and forced if you try to select multiple letters in this way, e.g. if you use "odd jobs" to mean only the odd-numbered letters of "jobs".
From the perspective of cryptic grammar, the word "jobs" is a single thing, albeit a thing made up of smaller things, and normal English grammar doesn't generally let us say "[adjective] [thing]" to mean a particular part of that thing. The string "jobs" is like a street because it's a single thing made up of several smaller things. If you wanted to refer to the odd-numbered houses of a street, it'd be natural to call them the "odd houses", but you'd never use "odd street" to refer to those houses collectively. By the same logic it doesn't really make sense to use "odd jobs" to collectively refer to the odd-numbered letters in that string.
While adjective-based constructions like "first day" and "central issue" are seen as bad cryptic grammar, adverb-based equivalents like "day, firstly" or "centrally, issue" are never really questioned. I find that a bit odd, because if you're talking about the first part of a day in real life then neither "firstly, day" or "day, firstly" is any more natural than "first day". I think the reason we accept the adverb forms but not the adjective ones may be that "first day" definitely looks wrong (because we know "first [X]" would normally mean an X which is first rather than the first part of X), but it's not clear that "day, firstly" would really mean anything in real life, so it's sort of an empty vessel which we can pour a special crossword-specific meaning into.
Ultimately I think "firstly", "finally" etc are probably too useful for setters to give up, but they're also a useful reminder that not everything which is widely used in Standard Cryptic Grammar is simply copied over from ordinary English grammar.
Generally, verbs can't be used to point to particular letters, because none of the verbs we might be tempted to use mean quite the right thing. The verb "finish" is a good example: "finish race" might look like a way of instructing the solver to take just the last letter of "race", but "finish" doesn't mean to do only the last bit of something (try joining at the finish line and see if people think you've finished the race). The same applies to "conclude": "story concludes" doesn't work as a way to say that only the Y from "story" appears, because to conclude is to come to an end after first having had a start and middle.
I think the only set of verbs you can make an argument for here are the ones that mean to start/begin, but I know from past experience that many would reject these too. My argument is that you could tell someone to start or begin a race without requiring them to do the rest of it, so "begin song" is a reasonable way to instruct the solver to begin (and only begin) writing the word "song" in their crossword grid. We'd also understand "the song has begun" to mean that a song's earliest or opening segment has appeared, so I think "song begins" is also sufficient to say that the word "song" will begin (and only begin) by appearing the form of a S.
