Seat ten of the most tidy (7)
I believe the answer is:
neatest
'the most tidy' is the definition.
(I've seen this before)
'seat ten' is the wordplay.
'seat ten' anagrams to 'NEATEST'.
Though, I'm not clear how this is indicated.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for neatest that I've seen before include "best-looking desk, say?" , "Most smart" , "Seat ten (anag)" , "Most tidy" , "Most orderly" .)
