I really liked this, one of the best of the (Monday to Sunday) week. Plenty that needed a bit of thinking with some not so obvious bits of wordplay or defs including CALF LOVE, CUD for ‘Partly processed food’, IMPEACHED for ‘called into question’ and OCTAD for ‘Four pairs’. BATHOS is (another) one of those words which I can never remember the meaning of, even if ‘anticlimax’ can’t be too hard. Favourite was UNICYCLE.
I’m pretty sure the TO in STOIC is ‘almost shut’ as in “pulling the door to”.
A big thanks to Tees for such an enjoyable tussle and to scchua
Thanks, T and s!
STOIC: I considered ‘top’ as scchua has explained. In addition to meaning ‘put a lid on’, it could mean ‘to conclude’ (loosely meaning ‘shut’).
I parsed STOIC as WordPlodder. Never heard of CALF LOVE but, unfortunately, do remember that Donny Osmond song which I truly hated.
Another fine Sunday puzzle – my Yorkshire granny always asked us to ‘put the door TO’ so I had no trouble putting TO inside SIC (thus)
Thanks to Tees for another lot of Sunday fun and to scchua for the blog
Great fun. Many thanks to Tees and scchua.
I’ve come across TO meaning shut a few times before in crossword land.
Undone by a carelessly entered PATHOS instead of BATHOS – a pat being a soft hit – so a DNF! How irritating!
That said, not a duff clue in this first rate offering from Tees. Too many ticks to highlight though the biggest PDM was AIRPORT which was a laugh out loud moment too. Nice to see IMPEACHED without a reference to Trump! UNICYCLE is a delightful cryptic definition.
Thanks Tees and scchua
What postmark said in two ways, as I’ve always thought these were Cypriot ports 🙂
But not really. I got BATHOS from the def check, and as you say a top-notch puzzle. The TO thing seems right to me, as it means ‘ajar’ (but what do I know).
Thanks Tees and scchua.
A good Sunday puzzle from one of our Indy regulars with first place awarded to CUDGEL which conjured up images of all manner of disgusting food!
Thanks to Tees and to scchua for the review.
As jane says, a good Sunday puzzle from one of our Indy regulars. We took ages, though, to get AIRPORT – after getting GROUND CREW. Favourites were CUDGEL and SEDAN.
Thanks, Tees and scchua.
Thanks for the blog scchua. Typically excellent offering from Tees with much to enjoy.
If I’m being really picky, I might point out that a “bike” specifically has two wheels, though I suppose the word is commonly used to describe all pedal-powered vehicles so I’ll try not to lose any sleep over that one. Still a fine clue for UNICYCLE anyway, along with several others already mentioned.
I interpreted STOIC the same way as Wordplodder, but scchua’s version works too.
STOIC made me think of the old cod-Latin rhyme which ends in Marcus (Aurelius) sic in at. Just the reverse in this case.
Thanks Tees for the Sunday fun with SPEED LIMIT, CUDGEL, and ALMANAC among my favourites. I agree with WordPlotter in rating this one of the best crosswords of the week. Thanks scchua for the blog.
