A great crossword which I really had to work at. Took me twice as long as G and I put together.
Thanks Artexlan and Teacow
Dominates was a very neat clue – no obvious giveaway that it was hidden as the surface was so good
A really hard one today but I finished without understanding 26D. My knowledge of English slang isn’t all that great but the only definition of “bung” that I know is “he bung it in the bin” meaning “he threw it in the bin”.
9A – “Merlin” as a bird was new to me. I only know him as a magician.
Thanks Teacow.
I agree with Matthew Newell@1
My loi was AFTERS. I was foolishly thinking of golf courses.What an idiot.
Thanks to Artexlen for an ingenious puzzle and Teacow for an exemplary blog
I agree that this was a trifle harder than I expected but none the worse for that.
I liked HANDSOME, the surface for GREYBEARDS which made great use of that cheese, NEATNESS, MATTERED and AFTERS.
For ‘bung’, Fiona, think of a stopper in a bottle of wine or a cask.
Thanks for the challenge, Artexlen and to Teacow, as always for stopping the gaps!
Liked HAND, AFTERS and DISINCLINED.
DISINCLINED
Looks like a DD (one straightforward def and one cryptic def)
Lacking enthusiasm
being upright?
Thanks Artexlan and Teacow.
This one definitely required thought in places.
The English that was new to me was EASY GAME, DRESS DOWN FRIDAY (I have always heard casual Friday) and SETT (I am a stranger to the habits of the European badger). The existence and location of Victory was another learning opportunity. I needed Teacow’s help to parse SLACKS (which I always thought to be trousers, I am unclear about the baggy bit) and OTHER HALF.
I largely agree with the favourites mentioned so far. I best liked the surfaces of NONDAIRY, NEATNESS and MATTERED (LOI). I thought AFTERS was clever once I finally got it.
Thanks Artexlan and Teacow
Thanks Artexlen. That took a bit of work but I got there in the end except for the nho SETT. (I understand the occasional odd word due to grid constraints but ‘Seth’ or ‘sets’ could have done nicely.) In any event I thought this was very well-clued with my top picks being HAND, CONCERTO, MATTERED, the nicely hidden DOMINATES, DISINCLINED, and OTHER-HALF. Thanks Teacow for the blog.
I thought of SETT for 16a, but didn’t think hollow and apparatus were synonyms for sett and set so I didn’t write it in. My bad.
I especially liked the cheese and biscuits at 21a GREYBEARDS. Cheese and biscuits could also be the AFTERS at 27a. Apart from a bit of Brie in 20d DEBRIS I couldn’t see a cheese connection but I liked that clue anyway.
Thanks Artexlen for the challenge, and Teacow for meeting that challenge so well.
Most of this went in fairly smoothly apart from thw NE corner where we hot stuck for ages. We eventually got DOMINATES from checking letters but only later saw that it was a hidden. SETT was almost our LOI even though we guessed ‘articutaled’ was a homophone indicator. Actual LOI was down in the opposite corner – AFTERS; very neat once we saw it. Lots to like, though; cONCERTO and GREYBEARDS among our favourites.
Thanks, Artlexen and Teacow.
Never thought of sett! Also I thought sage was more green and so went off thinking about herb or even wise after badly assuming or men were PA s or dads! And that the clue was some British term for crackers! But thank you everyone!
