3993: Argentum by Radix

 

Radix gave us one of the most difficult puzzles of the year. This was a Playfair code which took some devious steps to solve. As is expected from Radix it was superbly crafted with excellent clues, however, I am sure that opinions on this will be widely divided.

The letters from extra words gave the message, “In four pairs, both words must be
permuted similarly, and one then encoded”. 

It was obvious that four answers stood out as being permutations of their definitions - (35ac ulnare, 39ac overslip, 21dn long-head, 27dn Riyadh). The entry was the form indicated by the wordplay. The diametrically opposite answers had to be permuted similarly and then Playfair-encoded, leading back to the original answers.

ULNARE → NEURAL (order 361542), forcing SPRENT → RTSNEP, whose encoded form had to be SPRENT. Hence, under the encoding, RT → SP, SN → RE, EP → NT.

OVERSLIP → SLIPOVER (order 56781234), forcing WINSOMER → OMERWINS, whose encoded form had to be WINSOMER. Hence, under the encoding, OM → WI, ER → NS, WI → OM, NS → ER.

LONGHEAD → HEADLONG (order 56781234), forcing CONSIDER → IDERCONS, whose encoded form had to be CONSIDER. Hence, under the encoding, ID → CO, ER → NS, CO → ID, NS → ER.

RIYADH → HYDRIA (order 635124), forcing WHARFS → SAFWHR, whose encoded form had to be WHARFS. Hence, under the encoding, SA → WH, FW → AR, HR → FS.

The code phrase, MINCE WORDS could be discovered (try using the Playfair solver at http://www.quinapalus.com/playfair.html ) and the unclued words could be completed - hint, talk, news, sign (all defined by “word” in Chambers Dictionary). The title ARGUMENTUM was also an anagram and solvers had to “permute argument”, ie, “mince words”.

Extra words in clues are shown in square brackets with the relevant letters in bold.
