What do we agree upon?

(removed, see Wikipedia_talk:Manual_of_Style/dash_drafting/discussion#What do we agree upon? Casliber (talk · contribs) 00:13, 3 June 2011 (UTC)[reply]

Text

En dashes (, –) have several distinct roles.

( facilitator note: keeping the items as subdivided as possible will make it much easier to determine consensus. Lumping items risks the need for dissecting out for who wants what. Casliber (talk · contribs) 21:06, 19 May 2011 (UTC)[reply]

Ranges

1. To stand for to or through in ranges (pp. 211–19, 64–75%, the 1939–45 war). Ranges expressed using prepositions (from 450 to 500 people or between 450 and 500 people) should not use dashes (not from 450–500 people or between 450–500 people). Number ranges must be spelled out if they involve a negative value or might be misconstrued as a subtraction (−10 to 10, not −10–10).

to/vs.

voting in this section has been replaced by itemised section immediately below collapse box, to better enable judging of consensus

2. To stand for to or versus (male–female ratio, 4–3 win, Lincoln–Douglas debate, French–German border).

  • Disagree. I am willing to permit this, but not to require it. #1 without this produces a useful distinction between dash and hyphen, so it is actively undesirable and a MOS which supported communication would advise against it. Septentrionalis PMAnderson 03:34, 19 May 2011 (UTC)[reply]
  • Agree. (As it seems Anderson does: this is currently permitted but not required.) — kwami (talk) 10:00, 19 May 2011 (UTC)[reply]
    Judging from the number of articles which were moved from hyphens to dashes with no prior discussion, I'd say this rule is commonly treated as requiring rather than permitting. What about replacing have with can have in #Text above? A. di M.plédréachtaí 12:34, 19 May 2011 (UTC)[reply]
  • Agree, but it would seem that we have at least two different classes of use here. We need to separate them if this discussion is to be meaningful. JeffConrad (talk) 19:33, 19 May 2011 (UTC)[reply]

(removed, see Wikipedia talk:Manual of Style/dash drafting/discussion#to/vs.)

  • Agree. This has strong support from the style guides on both sides of the Atlantic. Yesterday, when I opened Scientific American and noticed "predator–prey relationship", and in the prestigious US-based online journal PNoS noticed "protein–protein interactions" in an article title, I didn't blink. Many scientists are too busy to bother with professional typography – that's fine, they're not professional writers; let them stay in their labs. But the good publishing houses follow the style guides and do it properly, with professional editors to tweak the manuscripts of their authors. It's commonplace in the industry. Agree with Kwami's take. Tony (talk) 04:08, 28 May 2011 (UTC)[reply]
  • Agree. Very commonly accepted; best retained among MOS recommendations. NoeticaTea? 10:10, 29 May 2011 (UTC)[reply]
  • Agree. Pretty standard in style guides, except for Chicago. Agree on the "require/permit" distinction: no editor is required to enter en dashes (they can enter hyphens, just like they can enter misspellings); and other editors are permitted to change to en dash (like they are permitted to fix spellings); this distinction is not unique to dashes and such. Dicklyon (talk) 08:26, 30 May 2011 (UTC)[reply]
  • Agree. Nageh (talk) 19:48, 8 June 2011 (UTC)[reply]

(NB: Please comment agree/disagree in each section below)

This is used instead of an ordinary syntactic hyphen with modifiers consisting of nouns or proper names where the semantic relation is "between X and Y" or "from X to Y":
[6]  a parent–teacher meeting  a French–English dictionary  the 1914–1918 war
It can be used with more than two components, as in the London–Paris–Bonn axis. It is also found with adjectives derived from proper names: French–German relations. There is potentially a semantic contrast between the two hyphens [that is, between en dash ("long hyphen") and hyphen] – compare, for example, the Llewelyn–Jones Company (a partnership) and the Llewelyn-Jones Company (with a single compound proper name).
(CGEL [2002], p. 1762, Chapter 20, 8.2.2, "Hard and long hyphens" subsection "The long hyphen")

For the record, CGEL is published in America by Cambridge (New York), and is a pan-anglophone grammar, with editing and contributions from several countries. The chapter just cited ("Punctuation") is written by an American, a Briton, and an Australian. Where punctuation is not the topic under examination, the text uses various conventions, not always consistently. Here is something else affecting our topic, addressing coordinative adjective+adjective compound adjectives (again I underline something that has been disputed in our discussions):

[30]  bitter-sweet  deaf-mute  shabby-genteel  Swedish-Irish  syntactic-semantic
The components here are of equal status. The last two illustrate highly productive patterns, both of which are predominantly used in attributive function: Swedish-Irish trade, a syntactic-semantic investigation. In general these can be glossed with coordinative and: "bitter and sweet"; "deaf and mute"; etc. In some, however, there is an understood "between" relation: "trade between Sweden and Ireland".
(CGEL, p. 1658, Chapter 19, 4.3.1, "Adjective-centred compound adjectives", subsection "Adjective + adjective")

[Added later; and re-signed:] Significantly, in its own usage CGEL firmly supports the en dash with the general sense "between". It overwhelmingly uses en dash in such phrases as subject–verb agreement (p. 499 et passim); I have found no "between" cases in which it uses a hyphen instead. NoeticaTea? 01:50, 28 June 2011 (UTC)[reply]
  • Disagree. I personally prefer CMoS usage, being American. Although I quote CMoS 16th Ed. here, it jibes with my personal preference as well. From ¶6.80 "En dashes with compound adjectives": "An abbreviated compound is treated as a single word, so a hyphen, not an en dash, is used in such phrases as 'US-Canadian relations' (Chicago's sense of the en dash does not extend to between)." Also see the table on page 379 of the 16th edition (¶7.85), under "proper nouns and adjectives relating to geography or nationality". Where the first term is a prefix or unless between is implied, CMoS prefers an open compound; the table shows hyphens, not en dashes, for the between usage. // ⌘macwhiz (talk) 22:23, 25 June 2011 (UTC)[reply]

disjunctive "and"

split out to better judge consensus below. Apologies to all who've commented but please acknowledge each subsection

3. To stand for and between independent elements (diode–transistor logic, Michelson–Morley experiment). An en dash is not used for a hyphenated personal name (Lennard-Jones potential, named after John Lennard-Jones), nor a hyphenated place name (Guinea-Bissau), nor with an element that lacks lexical independence (the prefix Sino- in Sino-Japanese trade).

  • Disagree in part. Permit, not require, although the specific use for multiple proper names is worth mentioning, because the contrast with Lennard-Jones is a real differentiation of meaning. Septentrionalis PMAnderson 03:34, 19 May 2011 (UTC)[reply]
  • Agree. Reworded as 'disjunctive and', as that's when it would be used. Not sure of the exception for affixes. How robust is that? — kwami (talk)
    I don't think I have seen dashes after stuff like Sino a non-negligible number of times (i.e., not significantly more often than I have seen a space after that). A. di M.plédréachtaí 12:41, 19 May 2011 (UTC)[reply]
  • Eleven hits on WP:CREDO on "Michelson–Morley" (searching with quotes and either a hyphen or a dash); 6 non-AmEng pages give the dash, and all the AmEng hits use a hyphen. - Dank (push to talk) 14:36, 19 May 2011 (UTC)[reply]
    • Replying to no one in particular: would more examples be helpful? - Dank (push to talk) 20:07, 19 May 2011 (UTC)[reply]
      Perhaps, but would it not be simpler to list the positions of popular style guides? Absent a very large sample of published sources, Google hist, or whatever, the results would seem dubious. JeffConrad (talk) 20:11, 19 May 2011 (UTC)[reply]
      Works for me. - Dank (push to talk) 20:45, 19 May 2011 (UTC)[reply]
      It seems to me that this might be worthwhile for every usage (properly broken out, of course). But it’s also a fairly significant undertaking; would anyone pay any attention? JeffConrad (talk) 20:41, 20 May 2011 (UTC)[reply]
  • Agree. Again, if we have partial agreement, we need to separate the uses. JeffConrad (talk) 19:34, 19 May 2011 (UTC)[reply]
  • Agree; See additional comments and reasoning above in to/vs.. Otr500 (talk) 13:05, 20 May 2011 (UTC)[reply]
  • Agree: supported widely by authoritative guides in North America, the UK, and other countries. Furthermore, no WPian has ever been at risk of a negative comment – let alone a back-street mugging – for using a hyphen (or a space or a word-jamming) instead of a dash; but just as the best professional publishers do, we have editors who don't mind fixing typography. I believe this attention to detail aids readers' comprehension, even if they're not schooled in the precise usage themselves, and makes our text look good to readers.Tony (talk) 04:08, 28 May 2011 (UTC)[reply]
  • Agree. This is similar to the preceding point, and the two could be made a little clearer if they were merged. I'd like us to simplify the text, but add extra examples showing concretely what MOS calls for. The ACS Style Guide, referred to at WT:MOS on these matters, supports this point; and it gives enough examples so that no one is in doubt. We should study it as a fine example of lucid exposition. NoeticaTea? 10:10, 29 May 2011 (UTC)[reply]
  • Agree. Pretty standard in style guides, except for Chicago. Dicklyon (talk) 08:26, 30 May 2011 (UTC)[reply]

( facilitator note: if you think there may be variance in views on the two items within this section, then I strongly suggest we split this now to clarify consensus, we ok with this? Casliber (talk · contribs) 21:08, 19 May 2011 (UTC)[reply]

I have suggested breakouts on the main Talk page; they’re not necessarily the only way to do it, but they could serve as a starting point. JeffConrad (talk) 23:12, 19 May 2011 (UTC)[reply]

To separate items in a list

superseded and split out below. Apologies to those who've commented already - please comment in each section

4. To separate items in a list—for example, in articles about music albums, en dashes are used between track titles and durations, and between musicians and their instruments. In this role, en dashes are always spaced.

  • Agree, although it is largely a part of 6 below. Septentrionalis PMAnderson 03:34, 19 May 2011 (UTC)[reply]
  • Agree, and agree with it being merged w 6. — kwami (talk) 10:00, 19 May 2011 (UTC)[reply]
  • Redundant with 6. A. di M.plédréachtaí 12:43, 19 May 2011 (UTC)[reply]
  • It's understood that in list-y and tabular contexts, the rules aren't the same. - Dank (push to talk) 14:37, 19 May 2011 (UTC)[reply]
    Could you give an example? JeffConrad (talk) 19:26, 19 May 2011 (UTC)[reply]
  • Neutral; the main need is a better explanation and example (or link to one)Agree that it should be merged with 6. JeffConrad (talk) 19:26, 19 May 2011 (UTC)[reply]

facilitator note: if you think there may be variance in views on the items 4 and 6, then I strongly suggest we keep separate to clarify consensus. Casliber (talk · contribs) 21:10, 19 May 2011 (UTC)[reply]

I’m not sure I completely understand the usage, which is why an example (or a link to one) would help. If the usage is what I think, it is just an alternative to a unspaced em dash—I’ve seen many examples of the latter. Again, we need to understand what we’re discussing before we can discuss it effectively. JeffConrad (talk) 23:08, 19 May 2011 (UTC)[reply]
  • Agree. Jeff's comment suggests it should be clarified: "in a bulleted or numbered list". Tony (talk) 04:08, 28 May 2011 (UTC)[reply]
  • Agree. But this is a fairly arbitrary matter of choice for the styling of lists; there are no strong precedents to follow or to care about. The intention should be made clearer, that's all. NoeticaTea? 10:10, 29 May 2011 (UTC)[reply]
  • Agree. Just an em dash style alternative; merge with 6 would be fine. Dicklyon (talk) 08:26, 30 May 2011 (UTC)[reply]
(please clarify acceptance of each section, and style below)

In compounds whose elements themselves contain hyphens or spaces

split out below. please comment in each section

5. In compounds whose elements themselves contain hyphens or spaces (the anti-conscription–pro-conscription debate) and when prefixing an element containing a space (pre–World War II technologies, ex–prime minister) – but usually not when prefixing an element containing a hyphen (non-government-owned corporations, semi-labor-intensive industries). However, recasting the phrase (the conscription debate, technologies prior to World War II) may be better style than compounding.

  • Agree in small part. (the anti-conscription–pro-conscription debate is valid usage; ex–prime minister is eccentric, and ambiguous with 2 and 3; if it is doesn't need to be done before a hyphen it doesn't need to be done at all. The last sentence really ought to be closer to don't do this if you can avoid it. Septentrionalis PMAnderson 03:34, 19 May 2011 (UTC)[reply]
  • Agree. Disagree with Anderson's understanding: this is not ambiguous w 2–3 if those do not apply to affixes, as we currently have it. The reason not to apply to non-government-owned corporations is simply that it's not visually intuitive and it seldom disambiguates. (Several style guides recommend the dash in such cases; others comment that such a convention is largely pointless.) — kwami (talk)
  • Chicago says, "... only when a more elegant solution is unavailable" (rarely), and Chicago is the most pro-dash of the popular American style guides. - Dank (push to talk) 14:54, 19 May 2011 (UTC)[reply]
    Again, we have more than one type of use. Chicago’s long-standing example of quasi-public–quasi-judicial body is indeed much better given as quasi-public, quasi-judicial body. But post–Civil War is perfectly OK, and is consistent with many other US style guides. JeffConrad (talk) 19:42, 19 May 2011 (UTC)[reply]
    It's not okay with Chicago, which advises that we work around it when possible, and it's possible here ... "postwar", "after the Civil War". I'm not sure if we're talking about the same US style guides; I'm talking about guides that writers are told they have to follow whether they like it or not if they want to get their book or article published in the US. I covered AP Stylebook, NYTM, Chicago, APA Style and MLA Style here, which more or less covers the landscape, but there are other US guides that are compulsory for specific segments of writers, and if anyone wants to throw them into the mix, please do. - Dank (push to talk) 20:32, 19 May 2011 (UTC)[reply]
    It depends on what the meaning of it is . . . The problem here is that we have at least two types of usage; if we judge by the examples, Chicago appear to deprecate only the combination of hyphens and dashes (OSM doesn’t even allow the combination). Perhaps we should separate the two uses.
    As for style guides, add Garner’s Modern American Usage and Merriam-Webster’s Manual for Writers and Editors as endorsing this usage; Words into Type and the APA style guide are silent.
    I question the applicability of the AP and NYT guides here—this isn’t a newspaper. And as I mention elsewhere, I′m leery of anyone who suggests using an en dash for a minus—the two characters clearly are not the same (– −), though the difference may matter less in a newspaper than in a technical book. JeffConrad (talk) 23:45, 19 May 2011 (UTC)[reply]
  • Agree. Pmanderson′s characterization of ex–prime minister as “eccentric” strikes me as eccentric. JeffConrad (talk) 19:42, 19 May 2011 (UTC)[reply]

(removed, see Wikipedia talk:Manual of Style/dash drafting/discussion#In compounds whose elements themselves contain hyphens or spaces)

  • Agree. [Could someone put the blowout above under a collapsible banner?] It's been around in US style for a long time, and Dank, I don't see much difference between the MoS wording and that of Chicago MoS and other US style guides: it's typical to find "reword where possible", although you can't always do it. Less common, but still used, outside North America. Tony (talk) 04:08, 28 May 2011 (UTC)[reply]
  • Agree, with reservations. This usage is definitely American, as New Hart's simply notes without recommending it for use. But American guides disagree sharply over the details; and like the contested spacing of en dashes below, if it is employed mechanically it may distract or mislead the reader. We should eventually insert some sort of proviso or caution, for this point and the later point about spacing. NoeticaTea? 10:10, 29 May 2011 (UTC)[reply]
  • Agree. As an American, I'm not used to the spaced version, but I see it's in other guides, and it does make logical sense. I don't think it should always be used, e.g. probably not in "New York–London flight", and that rewritng to avoid it is often a good idea. Dicklyon (talk) 08:26, 30 May 2011 (UTC)[reply]

Stylistic alternative to em dashes

6. As a stylistic alternative to em dashes (see below).

I thought AWB fixed this automatically, but I can't get it to do it now. AFAIK spaced hyphen is simply an approximation of spaced en dash. — kwami (talk) 18:04, 4 June 2011 (UTC)[reply]
I can't say I agree. I'm certainly not a linguist, but I do spend a lot of time reading American legal documents, and I'd say that spaced en dashes are used at least twice as often as unspaced em dashes in most things I read. AgnosticAphid talk 04:50, 30 June 2011 (UTC)[reply]
To what types of legal documents do you refer? I’m hardly an expert on such things, but I can’t find any examples of spaced en dashes in the last couple of volumes of United States Reports, and don’t recall seeing them in earlier versions. And the spaced en dash finds no support in Garner’s A Dictionary of Modern Legal Usage. JeffConrad (talk) 08:17, 30 June 2011 (UTC)[reply]

6.1 Follow-up question. In names such as "Harry Potter and the Deathly Hallows – Part 1", where the horizontal line is used to separate parts of the name, what kind of line should be used (spaced hyphen, spaced en dash, unspaced em dash, ...)? For discussion, see here.

But Jeff, the spaced hyphen looks bad, don't you think? It would be the last on my list of allowables. Tony (talk) 05:59, 18 June 2011 (UTC)[reply]

Spacing of endashes

Split out below. Apologies to those who've commented and can you please recast in each section below

Disjunctive en dashes are unspaced, except when there is a space within either one or both of the items (the New York – Sydney flight; the New Zealand – South Africa grand final; June 3, 1888 – August 18, 1940, but June–August 1940). Exceptions are occasionally made where the item involves a spaced surname (Seifert–van Kampen theorem).

  • Disagree with the exception "when there is a space"; an ingenious invention to avoid the problem with the New Zealand–South Africa grand final, but artificial.[Who wrote that?–Noetica. It was Septentrionalis, when he first created the page. Signed, Art LaPella]
    I agree that we should avoid artificial inventions. I have no idea whether this is artificial or not. ErikHaugen (talk | contribs) 20:10, 19 May 2011 (UTC)[reply]
  • Not sure, probably simply because I'm not terribly familiar with this usage. But it would seem to warrant consideration to resolve potential conflict with 1–3 and 5. (Anderson, all punctuation is artificial.) — kwami (talk)
    • Only to those who will not use punctuation to show the natural flow of thought and speech; that punctuation is no more artificial than speech. Septentrionalis PMAnderson 23:00, 20 May 2011 (UTC)[reply]
  • Disagree. The spaces in such situations are very rare in the literature, and hence unfamiliar to readers and potentially confusing, especially in articles which also use spaced en dashes as em dashes substitutes. A. di M.plédréachtaí 12:59, 19 May 2011 (UTC)[reply]
  • Let's agree on en-dashes before we tackle the spacing. - Dank (push to talk) 14:58, 19 May 2011 (UTC)[reply]
    Can we not walk and chew gum at the same time? This would seem a simple example. JeffConrad (talk) 19:50, 19 May 2011 (UTC)[reply]
  • Disagree on the exception. This usage is rare in published works (at least any that I′ve seen), and is at odds with every style guide that I’ve read. JeffConrad (talk) 19:50, 19 May 2011 (UTC)[reply]
  • Disagree. My Least favorite part of the guideline, as it introduces inconsistent formatting for equivalent constructs based on a rationale that is very weak and isnt attested in the majority of usage. oknazevad (talk) 17:23, 24 May 2011 (UTC)[reply]
  • Yes, it's too inflexible, and needs major loosening-up; but spacing in date-ranges is widely practised in English and is universal on WP, apparently without a single complaint; this should be the firm exception. Could I suggest the following?
En dashes meaning "to", "and", "versus" or "between" are unspaced, except when there is a space within either one or both of the items in a date (June 3, 1888 – August 18, 1940, but June–August 1940); spaced en dashes may be used between groups of numbers and words to avoid implying a closer relationship between the words or numbers next to the en dash than between each of these and the rest of their groups c. 1450 – c. 1650, not c. 1450–c. 1650.
The last sentence is based on the authoritative Butcher's copy-editing, which has long had flexible and intelligent advice on this, and is mirrored in several other important guides. Tony (talk) 04:08, 28 May 2011 (UTC)[reply]
Sounds good to me. ErikHaugen (talk | contribs) 19:12, 28 May 2011 (UTC)[reply]
Agree, with reservations. I've thought for a long time that this needs reining in, but the climate was not right. Now that we have a methodical process, we can adjust such things. This usage is really effective for displaying ranges of full dates, and in that capacity it has pretty good acceptance in guides (other than in America), and even more in actual use (birth and death dates in biographies, especially). For certain complex headings it is valuable too, where the items to be related are already unusually complex. But it doesn't work well in running prose, and we can work on that. NoeticaTea? 10:10, 29 May 2011 (UTC)[reply]

En dashes in article titles

When naming an article, do not use a hyphen as a substitute for an en dash that properly belongs in the title, for example in Eye–hand span. To aid searching and linking, provide a redirect from the corresponding article title with hyphens in place of en dashes, as in Eye-hand span.

That in most cases making a distinction is not important

This page isn't about the strength or policy status of the MOS as such as this is beyond the scope of this dispute.

That is, this is all a matter of Big-endians v. Little-endians still.


Yes, this case is about the strength and policy status of MOS.

I agree with Dick. No one wants to suppress any issue (whatever the hell this one is exactly; the insiders' Wiki-jargon doesn't help).
