Thanks Anto and scchua
I got 1a and 1d first, so was expecting a musical theme, but I don’t think there are any more.
Some odd ones. NON-ALLIED isn’t a common expression. I know that “present” gives PRESSIE, but I’ve only heard and seen it as “prezzie”. “Currency” in RED CENT seems to be doing double duty, to give “cent” and also “currency has little value”.
Pedant’s corner: as the Earth is an oblate spheroid, the North Pole is actually one of the lowest places (as in closest to the centre) on the planet’s surface.
Very enjoyable. My favourites were NORTH POLE, GENTS, ELLEN, SEND-UPS, RESIDUE, SCOOP.
New word for me was OROTUND.
Thank you Anto and scchua.
A much better effort by Anto this time around. Favorites were ANSWERS and RACONTEUR. Didn’t know OROTUND, but it was clear from wordplay and crossers. Thanks to Anto and Scchua.
At the tough end of the Quiptic range, I found, with some unfamiliar words (orotund, red cent, elision, non-allied), some tough clues (edifice, residue, elision) and some dubious ones (that’s not how I pronounce raconteur or spell prezzie).
And I have an additional pedant’s objection to calling the north pole “high”: there’s nothing physical about the earth that means “north” should be upwards, other than outdated eurocentrism.
I agree that was more of a work-out than expected for a quiptic, with a good variety of clue types. “sion” is more commonly a boy’s name (both in Jewish and Welsh naming traditions) being yet another variant on John (like Sean) so that threw me as i was looking for “ffion” (having the i and o crossers). Other than that, I learned a new word (“orotund”) and had to dig deep for “red cent” which I agree was weak, given the overlap in the word “cent” in the wordplay and the definition.
Anyhow, thanks Anto – a witty and smooth puzzle to kick off the week, and thank you Scchua for blogging it.
This was a mixed bag, but that was part of its charm. At first I thought there was a musical theme, though I’m unsure whether only six answers is enough to call it that. Theme-let, perhaps. I grinned at GENTS & NORTH POLE (yes, I do know that there is no ‘up’ nor ‘down’ in space and so no reason other than eurocentrism for the age-old habit of describing north as high or on-top, but this is a crossword for pity’s sake, and meant to be just a bit of fun). I enjoyed the clueing that led to ANDANTE, SMASHED, RACONTEUR & STARBUCKS, and liked the anagrams of TREADLE & RICOCHETS. I’d always spelled the name as “Siân”, but I’m not a welsh speaker and don’t doubt for a moment that other versions exist. I don’t think ITALICS is particularly cryptic, wasn’t wild about ELLEN, and have never, ever, encountered PRESSIE – only prezzie. But it was fun to solve nevertheless, so thanks to Anto for a pleasing start to the week, and to Scchua for help in parsing CUISINE & RED CENT (not being american, I’d never heard of the latter).
I completely agree with everyone else’s reservations: Sion is a boy (Sian is a girl); racon-tour maybe if you’re American; red cent maybe if you’re American; by sounds out large, Anto meant sounds out L; me is an example of a note, therefore needs a ? ; non-aligned, but not non-allied… Et cetera.
Much better than usual Anto. Non-allied is in one dictionary in “Onelook”. Agree about Sion and raconteur. Loved OROTUND. GENTS is an old chestnut. Thanks all.
17A. RAC + ON TOUR doesn’t give raconteur. Is it RAC + EN TOUR?
25D. One dictionary meaning of elision is “the omission of a vowel, consonant, or syllable in pronunciation”. But joining together?
VDS Prasad @9 I think your dictionary is right, but often elision in language is coupled with a requirement to join together. The most obvious examples to come to my mind are in French, where “je adore” is elided to “j’adore” with deletion (elision) of the “e” formally requiring the apostrophe and linking of the words. “Aujourd’hui” is a particularly interesting example, as it derives from “au jour de hui” and the single elision has led to a whole phrase being joined up.
I don’t think you could say the same of English so much, where elision is often a form of laziness in speech (“Oi ‘ad ‘istry today. It were borin'”) as the omission of the “o” in “history” is automatically followed by the rest of the word “closing up”. However, when applied to the more common contractions “I’m” and “We’re” then there is a similar joining up as in French.
Having said that, the second meaning listed in the OED online is “The process of joining together or merging things, especially abstract ideas” which presumably arises from such contractions as I mentioned.
Huge improvement on usual Anto. Enjoyed it and thought level spot on for quiptic
thezed @ 10. Thank you, I do see your point. But the solution doesn’t involve any omission, there is only joining together!
Coffee chain is unfair when welcoming brat doing handstand
I see nothing wrong with “red cent” being defined as it is. The phrase is not used literally very often. That is, “That ain’t worth a red cent” is not actually a statement of monetary value, so you’re safe regarding “currency” as part of the wordplay.
And I don’t understand the criticism of the RACONTEUR homophone. It works fine in my dialect, and is probably a lot closer in most others than your average crossword homophone (or anyway, I’ve seen worse).
Careless setting and careless editing not to check the Welsh name. I know we are a minority language but nonetheless deserve respect.
copland smith @7 points out the need for a definition-by-example indicator in 23a; one is also needed in 5d, as tenor is only one possible voice.
To pile on to the pedantry, the South Pole is quite high (about 2800 m), while the North Pole is at sea level. But I don’t really object to this. The imprecise definition of “elision” did rub me the wrong way.
On the whole, though, this was a fairly good Quiptic.
Great words, loved the headline surfaces. Many thanks, Anto and Sschua
