For PAWN, I would clarify the homophone is “STAKE,” but perhaps that was what you meant.
Otherwise, I think this looks good. Thanks.
I meant to add that I found this a bit of a struggle to solve. Some of the synonyms were not that obvious.
Enjoyed this on a chilly Bank holiday . I learnt that the item deposited with the pawnbroker as security for a loan is the stake.
Thanks Peto and Teacow.
REALISTIC
Parsed it as Cineraria@1
BANG UP
I think the def is ‘jail’ as a verb.
ON A TEAR
The def should include ‘showing’, I feel.
Liked CONFUSED, BELATED, REALISTIC, FAR AND AWAY and SPLATTER.
Thanks Peto and Teacow.
Thanks for the blog , agree with SM@3 , the last clue is partly a soundalike , steak say = stake = PAWN .
Enjoyable puzzle , lots of neat and concise clues .
SUIT
The def should include ‘with’, I think.
EIGHT
weight is consequence.
Tried to edit my earlier post, but the timer was faster than me.
I’ve never heard the expression “On a Tear” before, but then I’m only 72.
Eric@7
I am 81 and have nho of it either.
My Irish students say – On the tear – so similar .
I’d never heard of “ON A TEAR” either. ALI was central to me solving 2D. I found this quite heavy going, but fair and rewarding. Thanks PETO and Teacow.
Thanks Peto. I found this challenging at times and I needed a night’s sleep to finish my last six clues this morning. My favourites were SCRAPE, SUIT, REGULAR, WITHDRAW, and PEER. I couldn’t parse SPLATTER & PAWN. ON A TEAR (in Collins & Merriam-Webster but not in Chambers) is very commonly used in the US. Thanks Teacow for the blog.
Remembered ‘on a tear’ but not when or whence .. sport commentary maybe .. “so and so’s really on a tear today” .
Agree re 21ac, KVa @4, ‘in jail’ would be ‘banged up’.
Ergomania I’d nho, but I like it, quite fond of the old units like ergs and dynes (plus it has possibilities: ‘I’m’ around, ‘ritin’ article on independent area?)
All good fun, ta Peto and Teacow.
Found out challenging but got through it! Many thanks all
In 19d, why is odds == SP?
Thanks in advance.
SP = starting price
James @15. Thanks!
In 29a, why is Against == In anticipation of?
Thanks in advance.
I see what you mean john@17 .In anticipation includes anti which is against but then how does the rest of the clue work?
Think of building up a nest egg “against a rainy day”.
27dn is an unforgivably shit clue.
UTE = Native American? Are UK solvers expected to know that, FFS?
