Azed 
            said this:  Every clue should contain a definition or equivalent of 
            the answer plus a cryptic treatment of its component parts, and 
            nothing else. Every word in the clue must have a function as part of 
            the whole, and there should be no superfluous verbiage. 
            
            He is of course right, in that simply sticking in extra 
            words to give the clue more plausible surface (or literal) sense is 
            unfair: the solver has to second-guess any clue that does this by 
            ignoring the verbiage. In a sense clues like this are literally a 
            waste of time – since the solver will have been misled to no useful 
            purpose. Such sloppiness is rare (but alas not unknown) in 
            crosswords from respectable sources.
            As any setter with more than five minutes’ experience 
            will know, there are times when a clue can only be made to work well 
            if a word is inserted to link the wordplay and the definition. Take 
            this example:
            Bucket is white, we hear (4)
            for PAIL. We have the definition (bucket) and the 
            wordplay (a homophone of PALE) linked by the verb “is”. Taking 
            Azed’s statement at face value, the clue should 
            read
            Bucket white, we hear (4)
            but while the clue works cryptically, it doesn’t read 
            nearly as well as a meaningful phrase or sentence. Inserting “is” 
            here obviously helps the surface but this is not a case of putting 
            in unnecessary verbiage. At the very least “is” is valid as a kind 
            of equals sign, indicating equivalence between wordplay and 
            definition. It helps the solver work out where the break between the 
            definition and the wordplay occurs. That may not seem necessary in a 
            simple clue like this, but imagine that the setter had tried to 
            avoid the link word by phrasing the clue like 
            this:
            Bucket, we hear, white (4)
            The surface reading isn’t much (or any) better than the 
            previous example but this clue is unfair, in that we have no idea 
            whether the answer should be PAIL or PALE. Changing this to 
            
            Bucket is, we hear, white (4)
             pretty much solves the problem, although having gone 
            this far we might as well revert to the original as it reads 
            better.
            All 
            this is to show that link words can be harmless and 
            sometimes helpful or even necessary, for surface and other 
            considerations. I 
            should note here that I have not quoted Azed to disagree with him or 
            prove him wrong; although he successfully avoids link words in his 
            clues most of the time (that’s admirable) he does use them 
            occasionally himself.
            Conjunctions can be useful link words too. For example 
            
            Departed or remaining? (4)
            or
            Departed but remaining? (4)
            both 
            are possible clues to LEFT (the question mark in both 
            cases is just for surface sense). 
            Come in after fish and chips (9)
            is another valid example – if somewhat unoriginal – as 
            a clue for CARPENTER.
            All the examples above have a feature in common. The 
            only factor determining whether we have the order [WORDPLAY] [LINK 
            WORD] [DEFINITION] or [DEFINITION] [LINK WORD] [WORDPLAY] is the 
            surface sense; in the cryptic sense, either way round is possible. 
            The link word functions as an equals sign does in an equation, so if 
            A = B then B = A.
            There are other link words, often used by setters, 
            which are directional – in that it does matter which order the parts 
            of the clue are presented in. For example: 
            Elgar composed for royal (5)
            Not very exciting, but a safe and fair clue for REGAL. 
            This clue tells us clearly that we need to compose the letters of 
            ELGAR for a word meaning royal. 
            In this case, the clue is presented in the order 
            [WORDPLAY] [LINK WORD] [DEFINITION] and this is correct because the 
            link word FOR suggests that you need to solve the wordplay to get 
            the answer. Other link words which can be used in this way are 
            “gives”, “gets”, “produces”, “provides”, or “leads to”, and that 
            list is by no means exhaustive. Any word or phrase which suggests 
            that the wordplay results in the answer can be used, and the choice 
            of these will depend on how well they fit into the surface 
            reading.
            Now let’s look at another clue:
            Despondency from changing diapers (7)
            Here the clue tells us 
            that we get the answer (DESPAIR) from an anagram of DIAPERS and so is 
            rightly presented in the order [DEFINITION] [LINK WORD] [WORDPLAY]. 
            There are fewer alternative link words in this case and some of the 
            ones in common use are a little debatable – such as “of” and “by”. “Of” can mean “from” in certain contexts (“out of” = 
            “out from”), and “by” can mean “produced by” in that Hamlet is by 
            Shakespeare, but as any student of English knows, the exact meaning 
            of prepositions is extremely subtle and in my view, the use of both 
            of these in clues to mean “derived from” is rather tenuous. I use 
            them myself as a last resort, when all else fails, but don’t like 
            them very much. 
            What about a clue like 
            A 
            wise man for ages, possibly (4)
            There’s a potential problem here. As the clue is 
            written, it states that if you start with the answer SAGE (a wise 
            man) and jumble it up, you get AGES as an anagram of it. In other 
            words, we have the answer leading to the wordplay, rather than the 
            other way round. Does this matter? 
            The statement the clue makes is a true one. The word 
            SAGE does indeed need to be jumbled up to get AGES. There’s 
            certainly enough information in the clue for us to solve it – we can 
            simply see it as “Which word for a wise man is an anagram of AGES?” 
            and it’s hardly difficult to proceed from there. The clue is fair, 
            if rather untidily presented. 
            I have 
            seen 
            this sort of thing not only from the more “libertarian” setters, but 
            also from setters who pay scrupulous attention to detail in 
            other areas. When setting I try to avoid it as much as possible – 
            I am something of a perfectionist – but there are times when I 
            have an idea for a clue which I think solvers will greatly enjoy but 
            which will only work if presented as “answer leads to wordplay” or 
            “wordplay comes from answer”. I’ll spend a fair old while trying 
            to get it the “right” way round, but if I can’t get that to 
            work and I think it would be too great a shame to waste what is otherwise 
            a good clue, I’ll run with it and hope nobody notices. I would 
            be willing to bet that the majority of solvers won’t or if they do, 
            they won't be the least bit bothered about it! 
            
            Other link words which are of interest are “to”, “in” 
            and “with”. “To” is reasonable in some contexts as a “leading to” 
            link word; for example
            Settler resorted to snail mail (7)
            for LETTERS, but what about 
            Not allowed on the phone to ring 
            (4)
                   for BAND? I have a 
            problem with this one. The use of “on the phone” in conjunction with 
            “ring” may strike some as clever, but here the little word “to” 
            could be misconstrued as part of the infinitive “to ring” (as in to 
            phone). Misdirection is of course the aim of the setter but I 
            believe this is one misdirection too far and unfair, and I groan 
            whenever I see it (which is unfortunately quite often in some 
            quarters). 
            While on this point, what about 
            Crazy Cosima heading off hell for leather 
            (7)
            I 
            think this is fair, as although on the surface the link word “for” 
            appears to be part of a common phrase, the cryptic part is 
            unambiguous: make an anagram for COSIMA H to get a type of leather 
            (CHAMOIS). 
            The use of “in” as a link word was the basis of Monk’s 
            e-mail. I have always blithely used it, as many setters do, as a 
            non-directional link – in other words, being unconcerned about the 
            order of the wordplay and the definition. He suggested that as a 
            link word, “in” implies “found in” so clues of this type should read 
            [DEFINITION] in [WORDPLAY]. I think he’s right, and shall bear that 
            in mind when clueing in future. The only exception is when “in” 
            links two definitions of the answer, in which case the order doesn’t 
            matter.
            “With” as a link word has received much opprobrium in 
            recent times. I can’t for the life of me see why. “With” is a 
            synonym for “by means of” – you make an omelette with beaten eggs, 
            for example. So what’s wrong with 
            Run off with returning Eastern European 
            (5)
            as a way to get ELOPE from a reversal of E 
            POLE?
              I’ve never seen a cogent reason why 
            “with” is unsuitable as a link word. If this was just an idea put 
            forward by the small minority of Internet chatterers who seem to 
            delight in making petty criticisms without having written a single puzzle 
            themselves, I would ignore it. But the point has been made by 
            well-respected authorities on clueing, so I have (reluctantly) 
            avoided using it for some time now.
            Let’s move on – to link words which are, as Azed would 
            say, verbiage. I can think of a number of examples I have seen in 
            the national papers’ crosswords but I will invent my own here to 
            avoid any offence. Such as
            Mark’s back at school (4)
            Right – Monica resettled on island 
            (7)
            for 
            ETON and MINORCA. What possible function can “at” and “on” have as 
            link words here? They do not suggest equality, or that one part of 
            the clue leads to the other. They are simply stuck in there to give 
            the clue a decent surface reading. If this sort of thing were 
            confined to amateurs and new setters learning their trade, then I 
            wouldn’t mind. But it does rather annoy me to see this sort of thing 
            in the crosswords of quality papers.
            I 
            don’t want to resurrect the whole Ximenean/libertarian debate here. 
            But let me say this: since I wrote my two pieces on Ximenean clueing 
            a few years ago, it’s become noticeable that among some solvers and 
            setters the term “Ximenean” has taken on a somewhat negative tone, 
            rather in the way that “political correctness” and “Health and 
            Safety” now tend to refer to the ridiculously over-zealous pursuit 
            of what were originally well-meaning causes. “Ximenean” is now used 
            by some to evoke the idea of pedantic old buffers who want to put 
            crosswords in a glass case in a museum. In some ways this is 
            understandable – for example not so long ago I read a discussion in 
            which the classic 
            Bust down reason? (9)
               for BRAINWASH was declared by some to be 
            no good after all, as the definition (which is the whole clue, as is 
            the wordplay) doesn’t have an object. Well, maybe that’s technically 
            right, but the clue’s still a bloody good one and it’s this kind of 
            nit-picking that puts people off the whole Ximenean caboodle. That 
            is of course a great shame – Ximenes himself provided by far the 
            best guidelines for what makes for good cluemanship without being 
            prescriptive or preachy, and it’s hardly his fault that a few people 
            have taken the original ideas too far. 
               Without a doubt the greatest 
            contribution Ximenes made was to ensure that solving was enjoyable and satisfying. He 
            wasn’t laying down immutable laws or establishing some sort of 
            “cruciverbal correctness” – quite the opposite in fact. He was making 
            sure that solving puzzles was not a slog on account of the setter 
            being sloppy. 
            The examples I’ve given of bad clues for ETON and 
            MINORCA are simple enough that the redundant link words are unlikely 
            to cause many problems. In more complex clues, though, unnecessary 
            words like this could waste a considerable amount of the solver’s 
            time without offering any reward at all. I’ll admit that when I 
            (fortunately rarely) encounter this and other forms of sloppiness in 
            the nationals, my reaction is generally “why the hell do I bother?” 
            By which I mean why do I bother taking so much time – sometimes to 
            the point of spending a whole morning on just two clues – to do my 
            best to make my clues as neat and tidy as possible? I’m not saying 
            all my clues are good – far from it. I’ve written plenty of so-so 
            ones and some clunkers too, but I like to think that those clunkers 
            were at least fair clunkers. It’s not just me of course – the vast 
            majority of setters take pride in their work and will wrestle with a 
            recalcitrant clue until they’ve got it absolutely right. 
            
            Let’s 
            leave the 
            rant there and sum up. In an ideal world, there wouldn’t be any 
            need for link words. In practice, many clues do require some sort of 
            link between wordplay and answer, and there are quite a few words in 
            the English language which perform this task neatly. In a number of 
            cases, these words are directional in the sense of [ANSWER] comes 
            from [WORDPLAY] or [WORDPLAY] leads to [ANSWER]. Ignoring the 
            directional nature of such link words does rather detract from 
            the elegance and neatness of the clue, but sometimes the setter 
            can get away with this if the clue is in other respects a very 
            good one. It is wise, though, to take to heart the quote from Azed 
            at the start of this piece and not insert redundant words into the 
            clue just to make it flow better. Even if many solvers don’t notice (or care 
            about) these last points, the setter's aim is to use the versatile 
            and rich English language to provide cryptic instructions to the 
            solver, and the more accurate those instructions are, the better all 
            round!
