COTD: TURNIPS (Two twists in the tale)!
Liked SHOE and EVENS.
Thanks Bobcat and Teacow!
A minor observation:
LIFT-OFF
Def: Countdown to end with this
Thanks KVa@2 – have amended the LIFT-OFF definition
Several NHOs — Hera, DECREE NISI, ABLATIVE, Del Boy. And I was unaware of this meaning of retort. TURNIPS was clever.
I also had a long list of NHOs, slightly different to GDU@4’s. Aside from that, I do not have much to say about this one
Thanks Bobcat and Teacow
Very enjoyable. Quite tightly clued and a mix of straightforward and tussles. VIRGINIA, SEETHE and TURNIPS my podium.
Thanks Bobcat and Teacow
Thanks Bobcat. This was a mixed bag for me — I enjoyed some clues like VEILED, ABLATIVE, PATHFINDER, RENEGE, EXTROVERT, and ANTI-WAR but others like RETORT and TURNIPS were incomprehensible to me. I eventually revealed five clues in total so this was not a good outing for me. Thanks Teacow for the blog.
An enjoyable challenge, with TURNIPS the most devious, and my favourite.
My LOI RETORT took me ages, and went in with a distinctly raised eyebrow. I thought that had to be the answer from quite early on, yet couldn’t properly justify it. Partly because I’d never heard of the lab equipment (fair enough), but also because only the ‘T’ is the heart of TROTTER (a 7-letter word), not TT.
Thanks Bobcat and Teacow.
All solved without help, although there were a few chewy clues. We liked HABANERA, PATHFINDER and TURNIPS. We couldn’t see the parsing of RENEGE, our LOI – we saw ‘gene’ reversed in the answer and wondered if that was the ‘nature guide’ but we couldn’t make the rest fit.
An enjoyable solve; thanks, Bobcat and Tracow.
Thanks for the blog, good set of neat clues . I liked the Olympian for HABANERA.
PATHFINDER could have had a link to Mars , replace guide by rover.
Thanks BOBCAT and TEACAL.
Can anyone enlighten us on the italicised first words of 1A, 8D and 20D in the print version?
Piratewatch@11 The reason for the italics is that, for the purposes of the surface readings of the clues in question, Apple (the IT company), Grove (the dictionary of music and musicians) and Countdown (the UK TV show) are all references to names rather than to the dictionary meanings of the words.
Oh, that reminds me – would someone please explain the connection between 3D & 4D, which appear to be connected by ellipsis?
Really enjoyed this and got much of it but didn’t know what a del boy is and why is Gen the lowdown? But thank you! Always glad to learn here
Just listened to the habanera from Carmen played on the ocarina. Sounds pretty good.
Martyn@13, as far as I can see, the ellipses are there only because the two clues together make a single sentence.
I enjoyed this one. 11a DECREE NISI was my initial favourite, for the good anagram and excellent surface. I couldn’t parse 8d TURNIPS, but when I saw Teacow’s explanation it became my second favourite, so thanks to both Bobcat and Teacow for the fun.
Anil@14 , GEN is a word mainly seen just in crosswords. It is the news , the gossip , the lowdown , whispered between conspirators.
