The HB being the pedant hang-out that it is, I am sure this has been covered already, and has probably caused a long string of argumentative annotations somewhere. However, searching for "and/or" fails because both words are stop words. So.
The phrase "and/or" in non-technical writing irritates me, because it is wrong in several ways.
First, it looks ugly.
Second, the "/" means "or" (in order to avoid writing "and or or"), but we never use the "/" in this way in normal prose. Shakespeare didn't write "To be/not to be."
Third, the written "/" is silent - when you read "and/or" aloud you usually just say "and or". So what's the point in having it there? Alternatively, you might say "and stroke or", which is even more ridiculous comma when you think about it period
One way out of this would be to adopt Boolean logical conventions, wherein "or" would be replaced by "exor" (would you like milk exor lemon in your tea?), leaving "or" to mean "either or both" (would you like milk or sugar in your coffee?). However, this is clunky because the new word, exor, would be used much more often than the old word, or.
Another solution, recommended by many style guides, is to recast the sentence ("would you like milk, sugar or both in your coffee"), but this is long winded.
Why, then, do we not simply permit the word "andor" to exist, for use in those situations where you want to make it clear that either or both options can apply, and where "and/or" is used at present?
"Andor" is not an ugly word, nor is it difficult to pronounce. In speech, it is how we usually pronounce "and/or" anyway.-- MaxwellBuchanan, Jun 29 2012 http://linguistics....ve-and-exclusive-or [hippo, Jul 02 2012] Back in the day, it was borne in upon me that i overused the word "therefore", so i adopted techniques to avoid it, eventually compiling a list of other ways to express the connection. "Or" without "either" usually carries an inclusive connotation. However, there are other ways to approach this. One of the less obvious ways of doing this is to select functionally complete operators and reconstruct the disjunction so as to produce the same truth table as inclusive or. The problem with treating the disjunction in this way is that it is hard to reach - the sequent constructed from nands is the second longest of all possible truth tables.
Another possible approach is to look at how other languages express it and translate loosely, or not at all. Latin has "aut" and "vel", whose second expresses the inclusive or. German has "bzw." - bezüglichsweise - to put it across.
There's also the so-called Färbung, which distinguishes "but" and "and", and "however" and "also". This was Freges rather inadequate attempt at accounting for the meaning of conjunctions without having to abandon the idea of truth tables.
Now, for fun, believe it or not, i once compiled two lists of constructions to replace "therefore" (which is sort of a fancy "then") and "and", wherewith i peppered my prose. The same could be done for andor, and in fact now will. Moreover, there could be variations of Färbung for andor for all i know, but i have yet to consider that. The difference would presumably be whether the disjunction was expected or not.-- nineteenthly, Jun 30 2012 OK, my bad - misremembered this. It's "beziehungsweise" and could be translated as "respectively", "also known as", "rather" (which sounds exclusive to me) and "more precisely", which is to andor as "but" is to "and" i think. Rather disappointingly, it can also mean "also".-- nineteenthly, Jun 30 2012 Seems useful; given the Tweet-style dreck now embodied in the OED, this can at least justify its existence.-- Phrontistery, Jun 30 2012 //Back in the day// knew it was you in 4! :)
what rhymes with orand?-- po, Jun 30 2012 [nineteenthly] I agree, "either" does modify "or" to imply "exor". However, "andor" to imply "or, not and" is a little more compact. Regarding other languages that seem to handle this better, I do feel that English ingenuity should be able to devise a word of our own. Given the state of the economy, I am reluctant to rely too heavily on foreign imports.
//what rhymes with orand// four and? As in "four and twenty blackbirds"?-- MaxwellBuchanan, Jun 30 2012 I think that the inclusion of 'either' confers exclusivity on the 'or', and in its absence it must be assumed to be inclusive. So no additional words are necessary. If we're making up words, I'd rather have a gender-ambivalent term for one person.-- Loris, Jun 30 2012 //So no additional words are necessary.//
And yet sees "and/or" written quite frequently. I agree, in most cases a simple "or" will suffice. But for those who currently feel the need to use "and/or", "andor" would be a more elegant alternative.-- MaxwellBuchanan, Jun 30 2012 // I'd rather have a gender-ambivalent term for one person.// How about "one person"?-- MaxwellBuchanan, Jun 30 2012 //would you like milk exor lemon in your tea?// has to be [marked-for-tagline]
//one person// ... one perSON... see the opression inherent in the system &c. &c.
//If we're making up words, I'd rather have a gender-ambivalent term for one person// How about “they”? e.g. “I hear a person moving around downstairs, they were making a strange scraping noise”. The advantage is that this form is already in fairly common use. The disadvantage is that it drives the pedants mad. Both of which constitute good reasons to deliberately use it I think.-- pocmloc, Jun 30 2012 The trouble is that inclusivity has to be agreed generally for "or" to work as "andor", and it tends not to. I think there should be some kind of coinage programme for all possible bivalent truth tables for functions with one or two inputs, and perhaps also a second set to express unexpectedness. Another thing is that connectives can sometimes sneak out and turn into other bits of languages. For instance "is different than" has the same truth table as exclusive or. Therefore, maybe there's a piece of lurking language which is already doing that job.
"Four and twenty" works in near-RP but not in Scottish English (as was, at least) or SE English with its etymologically correct "fower", a disyllable.-- nineteenthly, Jun 30 2012 // inclusivity has to be agreed generally for "or" to work as "andor"//
I'm not sure I follow. I'm just advocating that "andor" be used to replace "and/or", wherever the latter is currently used. "Or" will maintain its current usage - if used in an "either...or" phrase, it will be interpreted as exor; if used simply in "A or B", it will be up to the reader to interpret it as "exor" or "and/or" (as is the case at present). But where clarity is needed and "and/or" is meant, "andor" can be used.
For example: "To be or not to be" (open to interpretation, but clearly either...or). "Milk or sugar?" (open to interpretation, but clearly allowing for both) "You can add either milk or lemon" (clearly exor) "Porridge is made from crushed oats cooked in milk andor water." (explicitly stating that a combination may be used)-- MaxwellBuchanan, Jun 30 2012 Oh bugger. I said I'm advocating, which means I've Mornington Crescented myself.-- MaxwellBuchanan, Jun 30 2012 I was typing at [Loris], [MB], not disagreeing with you. After some thought, I've arrived at "at least one of" as a possible equivalent. On the matter of negation, it turns out that a few languages negate by turning a statement into a question because it's more polite than contradiction - when one contradicts, it could be seen as accusing someone of being a liar. Thus what could be done is to introduce an extra-polite set of conjunctions by turning negations into rhetorical questions. Find a way of saying something which is only true when both component propositions are false, make it a polite rhetorical yes/no question and you will have your andor in another form. That would be "Neither P nor Q?".
I will now go away, draw a big table, work out sixteen phrases, add another sixteen phrases for surprising conjunctions and finally, will i add neither sixteen nor thirty-two rhetorical question-based conjunctions? Will this neither see the light of day on the HB nor a blog? We shall see.-- nineteenthly, Jun 30 2012 Ah. I see. However, do not forget to make allowances for possibilities such as "milk, lemon or sugar?"-- MaxwellBuchanan, Jun 30 2012 It gets more complicated then. However, i have a result: andor is equivalent to "unless" with two arguments! All you need is "unless" with three or more arguments, like a list separated by commas with "unless" instead of "and" at the end, and you have your synonym for andor. This depends on the rather controversial acceptance of material implication, but provided you can swallow that, it will work. Trust me on this.-- nineteenthly, Jun 30 2012 [nineteenthly], I can think of no-one better to trust with this matter. Which raises another issue: if no-one can be trusted, does that mean that two or more can be trusted? This too needs clarifying.
On a tangential note, there is a sentence which contains no fewer than five consecutive "and"s: a landlord of a pub is arguing with the signwriter at work outside, and says "There needs to be more space between 'Pig' and 'and' and 'and' and "Whistle"."
One could likewise ask "Should it be 'and or or' or 'or or and'?"-- MaxwellBuchanan, Jun 30 2012 From Wikipedia, the free encyclopedia
Andor may refer to:
Andor (Wheel of Time), country set in Robert Jordan's The Wheel of Time novels Andor Technology, manufacturer of scientific digital cameras And/or, logical conjunction Andorian, Star Trek fictional race inhabiting Andoria (also called Andor) Númenor (or Andor), a fictional place in J. R. R. Tolkien's writings Waldo Zeptic, the Ambassador from Andor, in The Adventures of the Galaxy Rangers-- sqeaketh the wheel, Jun 30 2012 Imagine our disappointment when we discovered that this had only the briefest of references to Boolean operators.
The "/" operator (when not used as a file path infix) denotes Arithmetic Division.
In C and its descendants, there are clear discriminations between the Arithmetic and Logical operators, "&" indicating the Arithmetic "AND" function and "|" indicating the "OR" function.
Likewise, the Logical functions are denoted by "&&" and "||".
In either case the operator combination "&|" would be rejected by a compiler as nonsensical.
We suggest that the use of "and/or" in text could be neatly replaced by "&|", pronounced "ampersand pipe".-- 8th of 7, Jun 30 2012 [ of ], my understanding of this discussion is that it's dominated by Boolean algebra! On that matter, the exclamation mark is not intended to negate the first sentence of this annotation in an RPN sort of way.
On that subject, what i'm surprised to discover seems to be "unless" can be represented by "v". Apparently, the reason for the inclusion of the backslash in ASCII was so that "/\" and "\/" could be typed in ALGOL.
It might make sense to trust two when no-one can be trusted because contradictions in their testimony might enable one to reach the truth, so that's absolutely fine.
It also occurred to me that the antonym of "unless" ought to be "less" and therefore that there's a case for replacing the connective whose truth table is false unless neither are true with that. In other words, less is nor.-- nineteenthly, Jul 01 2012 Doesn't and/or really mean any? Whats the difference in saying "I want cookies and/or milk" than," "I want any cookies and milk.". Simply provide any cookies and milk to me you can't go wrong.-- rcarty, Jul 01 2012 It can have different equivalents in different parts of speech if you like. For instance, the adverbial equivalent of "and" is "also", and "but"'s equivalent is "however" there. "Any" is probably the adjectival version of "unless", if you see what i mean. In fact, on reflection "unless" is probably to "but" as "and" is to "andor" - it's asymmetrical as to expectation.-- nineteenthly, Jul 01 2012 //the use of "and/or" in text could be neatly replaced by "&|", pronounced "ampersand pipe".//
Thereby combining typographical uglitude with an increase in spoken syllables...-- MaxwellBuchanan, Jul 01 2012 Indeed - the EU "Ampersand - Pipe" directive will be along any day now ...-- 8th of 7, Jul 01 2012 Treating those characters as they are normally used in formal logic as opposed to programming, "&" and "|" are complementary - "&" is of course AND and "|" is NAND. Putting the two together fails to refer to truth-values entirely, if anything. If it's taken to mean the conjunction of AND and NAND, all its truth-values are false. If it's their disjunction, all its truth-values are true. If it's a composite symbol of some kind representing a logical connective, to my eye, used as i am to formal logic as printed and written by pen or chalk in the twentieth century, and in fact also on the screen of a VT220 come to think of it, but in a declarative rather than an imperative context, it looks like it means absolutely nothing. I imagine if you're used to something like C or related notation, it's inside your comfort zone.-- nineteenthly, Jul 01 2012 If we eliminate "or" and instead use "not and", will that work?-- tatterdemalion, Jul 02 2012 hmm... you realize there's two different types of "andor" as well....
Whole Cake & Ice Cream | Cake | Ice Cream | nothing.
Natural Cake & Ice Cream | Cake | Ice Cream.-- FlyingToaster, Jul 02 2012 I think you're all forgetting Andorra and its 100,000 inhabitants.
It's all wired with Cat A LAN, apparently.-- UnaBubba, Jul 02 2012 I'm in favour of pinching a word from another language - it is, after all, the traditional thing for the English Language to do when it runs out of words to convey concepts. From the linked discussion, I'd like to propose the Basque words "ala" (exclusive or) and "edo" (inclusive or), as Basque is poorly represented in English at the moment. Interestingly, Finnish seems to have three words for "or": "tai" (inclusive), "vai" (exclusive), and "eli" (equivalence - "It's a shop, or where people go to buy stuff").-- hippo, Jul 02 2012 //Cake & Ice Cream | Cake | Ice Cream | nothing// Come on, you know that is both humanly and physically impossible.-- pocmloc, Jul 02 2012 Yes, the English language is impoverished in this way but one only need go to Latin to find distinctive conjunctions of this kind, which were traditionally used in formal logic for this purpose and have contributed the V symbol - "vel".
I think of Nand as "is incompatible with". "Not both..and..." is probably the most straightforward form.-- nineteenthly, Jul 02 2012 // you're used to something like C or related notation, it's inside your comfort zone. //
Who would want to be anywhere else ?-- 8th of 7, Jul 02 2012 // How about "one person"?//
Ah. I think that will work nicely.
When writing a letter: ~ Dear one person Leslie Ambiguous-Firstname, ...
On the phone: ~ Hi I'm trying to speak to Tracy, is that person available?
Not stilted at all.-- Loris, Jul 02 2012 The best and simplest method of dealing with this would be to construct an array denoting each bitwise operation in sequence and then referencing its index. So for example, let's take two subjects, a and b, and construct a matrix such that r is the result: abf i = the truth-table(a,b,r) ------------- 0 (0,0,0) 1 (0,0,1) 2 (0,1,0) 3 (0,1,1) 4 (1,0,0) 5 (1,0,1) 6 (1,1,0) 7 (1,1,1)
This way, if I want to refer to milk abf(3,5,7) sugar. It becomes expressly clear that I'm happly to supply one, the other, or both.
Wider functions could be defined for arrangements of more than two subjects, but would be confined to usage by only the most pedantic.-- zen_tom, Jul 02 2012 Why does your two-bit truth-table have eight entries, zen_tom?
It looks to me like a three-bit table. Were you considering the tea as well?
The question "Would you like tea with milk or sugar?" provides five options: {tea alone, tea with milk, tea with sugar, tea with milk and sugar, no tea}. The alternative way to interpret what you say is along the lines of Mrs Doyle - whether tea will be drunk is not in doubt. You must have tea. You must also have one or both of milk and sugar.
Oh, and I think orand is better than andor.-- Loris, Jul 02 2012 It's a three-bit table because having a separate word for NOT confuses matters, and I don't want to get bogged down in any confusing negative/double negative territory, so the final bit there shows you the result expected from the combination of the preceding two bits. (Plus it makes the tacit assumption of a Non-Doylian Universe)
This allows you to answer the question "Would you like tea or coffee?" with the answer, "abf(0)" which would mean not only that you didn't NOT want either tea, coffee, but that nor would you not like both a cup of tea and coffee at the same time. That isn't of course not perfectly simple nor consise.
Vernacular usage would normally be limited to one of the odd-numbered indexes.-- zen_tom, Jul 02 2012 [z_t], i came up with a conlang which worked a bit like that once. Each proposition was a four-letter monosyllable like "tosk" which varied according to its truth table, and i arranged the alternatives so that each combination was easily pronounced.
The thing about "orand" is that it's on the brink of being a rhyme for "orange", but if it were to be the actual word "orange" it wouldn't be any more, so how about three conjunctions plugging gaps: "sporange", "spurple" and "chilver"? Three words then end up with rhymes into the bargain that way.-- nineteenthly, Jul 02 2012 "sporange" and "chilver" are real words, but "spurple"? You could have "hurple" or "curple".-- MaxwellBuchanan, Jul 02 2012 Kind of relevant:
Pooh always liked a little something at eleven o'clock in the morning, and he was very glad to see Rabbit getting out the plates and mugs; and when Rabbit said, "Honey or condensed milk with your bread?" he was so excited that he said, "Both," and then, so as not to seem greedy, he added, "But don't bother about the bread, please."-- spidermother, Jul 02 2012 Hurple is fine by me but your assertion that sporange is real I find startling. Is it just not pronounced like "orange"?
Edit: sporangium! How could I not have known about that?-- nineteenthly, Jul 02 2012 As long as we're discussing tea, milk and/or sugar, let's not forgot the Oreo.-- sqeaketh the wheel, Jul 02 2012 What about the Andeo?-- nineteenthly, Jul 02 2012 random, halfbakery
