12d Was Pasquale reading yesterday’s debate? And several others? Thanks, scchua. I struggled with this one.
Thanks Pasquale and scchua
Fairly straightforward except for the NW, where I failed on PURL and didn’t understand it even when I cheated – thanks, scchua. TEAPOY was a new word for me, but clearly clued. Favourites were DIATONIC for the nice misdirection of “do”, and GIBE.
[btw the Guardian published an apology for the “1 is a prime” error from a few days ago in its corrections column today. The clue had already been altered online.]
(scchua – misprint in 14a. SEANCE is losing “ce”, not “ch”)
Thank you sschua, look forward to the finished article.
Enjoyable puzzle again from The Don with a few less well-known entries such as ASSEVERATE.
I didn’t know purl as an edge, only as a beer so that took a fair while.
Also, although it went in easily enough, I didn’t recognise CONSTANCE as the city although I have visited that beautiful town (Konstanz) a number of times.
Failed on TRAY entering DRAY and being unable to parse either. I couldn’t get past U = bend.
Splendid job, thank you you, Pasquale.
Nice week, all.
MikeP @1 Yes, I wondered about that, I think it was a comment by Rishi. Using the ‘s’ off the end of a plural just seems a bit feeble.
Thank you Sschua and Pasquale. I’m a knitter and didn’t know a purl was an edge, so, like Muffin@2, I couldn’t understand it after cheating either! I liked 12d best.
(Apologies, scchua – I’m out for the rest of the day, so won’t be able to attempt your picture quiz.)
Very enjoyable – thanks to scchua & Pasquale.
I liked the hungry donkey at 18a.
For 26a I had SH in FLAY.
Many thanks to Pasquale and scchua.
Re 26a I too parsed like jkb_ing @9: I thought it was FLAY (“one”, i.e. a type of attack) containing SH.
Enjoyable puzzle, on the easier end of the scale for a Pasquale. As a follower of the turf, I’d never heard of ‘purler’, or, if I had, I’d imagined it was spelt ‘pearler’, as in the Aussie slang for something excellent. DIATONIC and INTELLIGENT were my favourites, the latter because it evoked memories of my Dad, who played a couple of times for Minor Counties v the touring side (those were the days) and knew all about the distinction between Gents and Players, having been invited to captain Warwickshire in 1955, in the days when the county skipper was still an amateur.
Thanks, muffin. 14a now corrected.
Thanks Pasquale and scchua.
I am convinced Ps crosswords are getting easier.
I took 9ac to be the R + AMBLE ie river Amble (in Northumbria)
Sorry, in Cornwall, not Northumberland
Thanks Pasquale and scchua.
Quite hard going for me, I must have met ASSEVERATE before, but it did not come to my mind. Should ‘may’ be included in the definition for HIGH WATER since it does not always leave a tidemark?
I especially liked PURL, MEMPHIS and DE LA WARE!
jkb_ing & Giudice, I think you’re right about 26across. The containment indicator would then be “in which one must keep”. I was fixed on giving an explanation for “one”.
Count me as another who needed aids to get PURL. I didn’t know it was an edge, and I didn’t know that meaning of “purler”, only ever having come across it before as “something very good” (I’ve never seen ulaca@11’s “pearler” spelling).
PURL was my LOI. I didn’t know it meant “edge” but once you’ve got two crossers in a four letter word, it didn’t take much to guess the answer. Otherwise I found this rather easy which is certainly not meant unkindly because there was a lot of fun to be had in solving this. Liked SEAN and DIATONIC amongst others.
Thanks Pasquale.
I thought there was a River Amble too – thanks Dave Ellison for the confirmation.
Without the checker, 18a could just as easily, if not more plausibly, be ASSOVERATE from the wordplay – this is what I first entered, which did me no help at all. Happened to be online so ‘check’ showed me wrong, but in the olden days I would have run to Chambers.
I’m putting myself down as a failure as PURL simply did not yield – like muffin I needed the blog to make sense of it.
Thanks to Pasquale and scchua. I had trouble getting started with this puzzle (at first nothing clicked) though eventually things improved. I’m yet another who had difficulty with PURL (my last in) because “purler” was new to me and FLASHY gave me trouble. ASSEVERATE was familiar from previous puzzles (though not from common usage) but I took a while seeing STRAITEN as a verb. All in all, a challenge but well worth the effort.
Not Pasquale’s most difficult, apart from PURL – PURLER was new to me in that sense, so that took some guessing and checking. TEAPOY at best vaguely familiar but fairly clued. Liked WEIGHT WATCHERS and DIATONIC
Thanks to Pasquale and scchua
Completely defeated by PURL, and aslo very glad that I didn’t sleepwalk into TEAPOT (but it was a close run thing)…
Thanks all
Tough but gettahle, although I failed with purl since I had no idea it meant edge!
There were some clever anagrams eg 21 ac ,11 ac.
Re 14A: ‘Church’ can be ‘CE’ can’t it? (Church of England)
I thought this rather weak compared to the usual Guardian standard – too many contrived surfaces for my liking and loose cryptic clueing e.g. FLY = attack in 26A.
Oddbod @25, I parsed 26a as SH in FLAY.
Loved ASSEVERATE. Hated HIGH as a synonym for school.
Thanks Pasquale and scchua
This one stayed one clue short from finished for a few weeks – yes … it was PURL. Finally, last night I found that it did mean edge … and looking up purler as a headlong fall confirmed it !
Now that there is a River Amble, 9a sits better with me – don’t know why I didn’t look it up myself – it would have been unusual for the Don to leave a loose one like that.
Lots of variety in the clue devices used here, especially liked DE LA MARE and TRIPPERS.
