For the benefit of non Brits ETON CROP is a severe hair cut and Barnet is hair in Cockney rhyming slang. In the other hand I was completely baffled by the Baltimore baseballer clue 5ac although the bird was clear from the crossers.
Yes, I enjoyed this too.
The two three-letter answers OIL and EEL provided a handy way-in to the grid while LETTERSET and SENTENCE were my favourites.
Thanks Pete and Cineraria.
ORIOLE is a funny sort of clue: baffling if you’re British, and a complete write-in if you’re American. Usually it’s the other way around. In a way there’s not enough there, since the baseball team is named after the bird, but I guess “flier” being used misleadingly does just enough to make it cryptic.
This occupied my lunchtime nicely while my grandson napped. A couple of NHOs: OBELI & DÉCLASSÉ, but both solvable from the solid clueing. Thanks, @PETO.
I’m a bit confused about 17. “on permit” suggests “let” comes at the bottom, not the top. The alternative, that “on” belongs with “dates essentially” strikes me as a bit forced.
Babbler@5: I read “on” in 17D as meaning something like “tacked on at the end.” I think that this is a permissible, if perhaps less common, cryptic usage.
So many wordy clues and so many obscure references meant a lot of guessing the answer first and parsing the clue later. I am afraid this was not my favourite type of puzzle. Thanks anyway Peto, and thanks to Cineraria for the blog
Thanks Peto and Cineraria
17dn: The correct usage of “on” to indicate juxtaposition is a hardy perennial. Some editors insist that X on Y means YX in an across clue and XY in a down clue, and setters intending to publish in multiple journals would be wise to stick to that, but the FT certainly allows XY or YX in any clue. For YX in a down clue, I find it helpful to think of the notion that something (paper, paint, an electric light bulb, etc) is on a ceiling if it is directly below that ceiling.
