?Sugar of lead
A tag has been placed against the use of sugar and flannel to seal the joints in the iron trough. The Royal Commission on the Ancient and Historical Monuments of Wales, which has done surveys, states that the joints were sealed with flannel, white lead (my emphasis) and iron filings. I was entertained by the possibility that the very widespread story of "sugar" may have come from some confusion with sugar of lead, but could find no evidence of this. Nonetheless, the Commission is a very strong source and "white lead" should go in. Question: do we keep the very popular sugar? --Old Moonraker (talk) 07:18, 15 March 2009 (UTC)
 * OK: done, leaving out all references to "sugar" (even sugar of lead). --Old Moonraker (talk) 21:51, 5 June 2009 (UTC)
 * Unfortunately the best ref for this is broken. I see "sugar" is still widely quoted, even in books, so I've scratched around for a couple more. I take it that these authors don't take sugar dissolved in their tea--217.155.32.221 (talk) 13:54, 9 August 2016 (UTC)

UNESCO application accepted
 It's been accepted, but I've no idea how to include that in the article. If someone could do it, it'd be brilliant thanks... Cieran 91 (talk) 22:31, 27 June 2009 (UTC)

Co-ordinates
Somewhere between entering the co-ordinates on this page and displaying on Google Earth there's a problem, as both the grid reference and the lat/long direct to the wrong locations. They also have the wrong but, strangely, not unrelated labels of "Shropshire Union Canal" and "River Dee". The link to Bing Maps seems ok. Anybody know what's wrong? --Old Moonraker (talk) 12:47, 30 June 2009 (UTC)
 * Email to Google Earth, standard "We investigate all data errors and pass all ... requests on to our data production team" response.--Old Moonraker (talk) 09:01, 1 July 2009 (UTC)
 * It's a GE problem. The co-ords are 52.97053, -3.08783 - that works just fine in Streetmap (at the 1:25000 level = proper OS map), the GE link drops on in at 52.956, -3.1306 - hence a bit off to the West. If one kills the "square" then there is a BAD picture link at the same spot entitled The Pontcysylite Aqueduct, LLangollen Canal, Wales - País de Gales - looks like GE is jumping to this picture placement box by mistake  Ron h jones (Talk) 20:38, 1 July 2009 (UTC)

Image placement
The re-arrangement and enlargement of images in this edit is contrary to MOS:IMAGE. Just two, from several contraventions: "Start an article with a right-aligned lead image or infobox" and "Avoid sandwiching text between two images that face each other". --Old Moonraker (talk) 10:38, 2 August 2009 (UTC)
 * Thanks for the fixes. The "Longton" and "Canal boat traverses" images are referenced in the text. Any objection to yet another reshuffle, to bring the pics next to their bit of the story? --Old Moonraker (talk) 11:40, 2 August 2009 (UTC)
 * Cancel my last: recent caption changes make this unnecessary. --Old Moonraker (talk) 11:53, 2 August 2009 (UTC)

Cost to build
> "£47,000 (£2,930,000 as of 2011)"

This statement on its own is somewhat curious. £3m today might not even cover the design work much less the cost of survey, construction, materials, insurance, fees, taxes, etc. Green Cardamom (talk) 05:38, 26 November 2011 (UTC)

Passing
I raise this after an IP query on Template talk:Infobox aqueduct navigable.

The infobox indicates boats can pass but as the Aqueduct is only 11-foot wide and narrowboats are about 7-foot wide there appears to be a problem. Is there passing places or some other explanation for the apparent problem? Keith D (talk) 23:41, 10 January 2013 (UTC)


 * Infobox previously had Passable? = No but this was displayed as Traversable? = No. Passable doesn't seem to be a valid parameter. Or is it a synonym for Traversable? Anyway, the aqueduct is traversable by boats and so I've changed Passable? = No to Traversable? = Yes. Two boats can't pass each other on the aqueduct as it isn't wide enough.Zin92 (talk) 06:34, 26 November 2015 (UTC)

Principal area categories
I was doing some categorisation work on scheduled monuments in Denbighshire and found the aqueduct listed there. Bit of research in Cadw records shows that its scheduled (as a monument) in Denbighshire and listed (as a building) in Wrexham county borough... A slightly odd position - whenever I've come across bridges over boundaries in the past they've usually been scheduled or listed in both principal areas.

I'm tempted to categorise as both a listed building and a scheduled monument in both Wrexham county borough and Denbighshire. Any thoughts/objections? Robevans123 (talk) 10:44, 4 May 2016 (UTC)

Etymology
Isn't the plural for "cyswllt" "cysylltiadau"? Let's not forget we also have the original Pont Cysylltau (which currently says nothing about its etymology. Martinevans123 (talk) 18:37, 8 January 2018 (UTC)
 * If you look on Google Books, the main sources for "cysylltau" as a word are 19th century guidebooks (most of them repeating each other) using it as a name for the aqueduct, probably due to a misunderstanding of the (very old) name 'Cysyllte'. If "cysylltau" was a common plural form of 'cyswllt' then I'd have expected it to appear more in dictionaries. As far as I can make out the original source of this confusion over 'cysyllte' and the idea of a 'junction' is a discussion on a phonetician's message board some years back. These things then tend to spread across the Internet.


 * As for the earlier road bridge, I've yet to find much evidence that its current name is anything but modern. Most of the sources, including those listed in the article, actually call it 'Pont Cysyllte'. CADW calls it 'Pont Cysyllte / Cysylltau Bridge', suggesting the latter is an anglicised form. I have a thought 'Cysylltau Bridge' is actually a kind of hypercorrection by English speakers assuming the word should end in '-au'.


 * "Cysylltiadau" on the other hand immediately brings up many citations as the plural of 'cyswllt'.Svejk74 (talk) 12:43, 9 January 2018 (UTC)


 * Thanks. I see you have now moved Pont Cysylltau to Pont Cysyllte. Martinevans123 (talk) 13:27, 9 January 2018 (UTC)
 * Yes, this looked to represent the sources better. I hope this makes things clearer!Svejk74 (talk) 13:29, 9 January 2018 (UTC)
 * Yes, I think it does, thanks. Martinevans123 (talk) 13:31, 9 January 2018 (UTC)
 * Not for addition to the page, but my own theory is that the placenane came from the old word 'swllt' ('shilling', 'wage'; pl 'syllte') with the conjunction 'cy'- Svejk74 (talk) 14:25, 9 January 2018 (UTC)
 * That's novel. You're suggesting there was a turnpike road here? I think swllt can also mean "swill"?! Martinevans123 (talk) 14:30, 9 January 2018 (UTC)
 * Something like that! Either makes more sense as a placename than the rather literary sense of 'connections' etc Svejk74 (talk) 15:32, 9 January 2018 (UTC)
