The high number of envelope clues made this puzzle a relatively kind solve overall, just right for a Monday.
Still, I needed to check the blog to confirm/clarify the full parsing of 3 and 9.
My favourite was the literary DO ONE’S NUT.
11’s ‘charm’ could only be OBI but that would be ‘obi-kazari’ while ‘obi’ on its own refers to the wide sash worn around the kimono-wearer’s middle rather than the charm (‘kazari’) suspended from it. Of importance to a friend of mine who specializes in the art of the kimono but of minor note only here in crosswordland.
An enjoyable offering.
Thanks to Peto and Teacow.
In Chambers, obi meaning ‘charm/fetish’ is listed as a separate meaning to ‘sash’.
I initially parsed HEARTACHE as in blog but preferred ‘A’ for ‘each’ + CHE for ‘revolutionary’.
If it’s in the dictionary, fair enough…
Got stuck on the parsing of KEYNOTE so tx Teacow. How does ‘how’ equate to ‘that’ in SHOWPIECE exactly? Liked AGA SAGA, OPOSSUM and SNAPPER UP in particular.
Thanks Peto and Teacow
11ac further to Hovis @2, Chambers 2016 p 1061 has
obi¹ witchcraft and poisoning practised in the West Indies, Guyana, etc; a fetish or charm
obi² a broad sash worn with a Japanese kimono.
Collins 2023 p 1373 has obi¹ and obi² the other way round, and (under obi²) is more specific that the charm relates to the form of witchcraft.
I’d also like someone to explain ‘how’ = ‘that’.
I spent ages trying to make HEARTACHE parse with ‘revolutionary’ = Che, but couldn’t see ‘each’ = ‘a’ so ended up parsing as in the blog. Not sure which I prefer.
Thanks Peto and Teacow.
17dn: I cannot find any dictionary support for “how” = “that”. The following two sentences seem apt for this discussion, but I think they are saying different things.
I do not see how it works.
I do not see that it works.
While I am back in, apologies for putting 11ac instead of 11dn in comment 5.
“That” is in Chambers as a definition for “how” at the end of the list for adverbs and conjunctions, but I cannot think of an example where they interchangeable.
Akin to PB@7’s suggestion, maybe as question and answer?: He is how old? He is that old.
Cineraria@8. Thank you for that. I do not know how I missed it, but I can see “that” in Chambers 2016 on p 739 under how¹.
Thanks Pelham @5 for clarifying satisfactorily the other sense of ‘obi’ as in witchcraft distinct from ‘obi’ as a Japanese sash. I didn’t know the former.
I liked SEE THROUGH and the use of Lorna Doone. I hope Roz is pleased to see the troops in GLORIES.
An enjoyable puzzle from PETO after Saturday’s wrestling match with GUY. Thanks, PETO.
(BTW: I keep getting a “403 permission denied” screen when trying to post. Can you fix that, please.)
A very approachable puzzle that provided a gentle start to the week. I needed internet research to solve AGA SAGA, then I could not parse it. Aside from that, pretty smooth sailing.
Thanks Peto and Teacow
