A lovely start to the week from Bobcat with his trademark nina to go along with 26a.
Favourites today included the neat SAVIOUR, TROPHY and AD NAUSEAM.
Thanks Bobcat and Teacow.
A bit of a battle I found. Liked detritus.
There’s much I don’t understand here.
Why is mavin “Trump’s expert”, rather than just “expert”?
Why is create “make a fuss” rather than just “make”?
And the description of a dumb waiter as an “agency” seems odd.
Thanks for the solution!
Steve@3… so MAVIN is American slang I think. CREATE is in Chambers as “make a fuss”
Ah OK thanks, I didn’t know this convention of [President’s] meaning [American word for]
Btw I thought the word was Maven, never heard of Mavin before. I assume it is in chambers etc as both spellings.
Thanks Bobcat for a top-notch crossword as expected. Favourites included RECRUIT, SAVIOUR, TANGENT, TENNYSON, & IMPOSTOR as well as the Nina which help me solve KINDLING. My only stumble was TOPICAL. Thanks Teacow for the blog.
25dn further to earlier comments: Collins 2023 p 1214 has “maven or mavin“; Chambers 2016 p 944 has them as “mavin or maven“. Both dictionaries mark the word as US, so a geographical indicator is required. Possibilities include the name of a real person or some sort of stereotypical nickname for the relevant area, or naming some location within that area. One that is definitely worth looking out for is a clue starting “Nice”, which could be hiding the capital N in the name of the French city. The indicator “Trump’s” chosen here is probably best thought of as a specific example of a much more general principle rather than a convention in its own right.
I have never, even once, seen MAVEN spelled with an I until today. I was also unaware it was an Americanism. Now I’m curious about the etymology, which I’ll go look up once I’m done typing this. (Edit to add: I looked it up, and of course it’s Yiddish, a source of so much specifically American English.)
The Nina helped this time; I saw the kitten poking his little pink nose out in time for him to help me get some letters in the southwest. I would never have parsed ATMOSPHERE in a month of Sundays, so thanks for that.
I found 24a outstanding – I don’t think that I’ve ever seen a double solution like that before
In 30a I didn’t like NOS being plural numbers but TEN being singular. One way or the other, the S isn’t properly accounted for.
A minor issue with 8d, geishas are normally girls now, but were originally men.
Thanks Bobcat and Teacow
My only quibble with this otherwise excellent puzzle is that the saint referred to in 24 was MOTHER TERESA.
A lovely puzzle. My only quibble is the same as Simon’s @11.
