The sun rises in due style - absolutely fresh (6)
I believe the answer is:
unused
'absolutely fresh' is the definition.
'unused' can be an answer for 'fresh' (I've seen this before). I'm not sure about the 'absolutely' bit.
'the sun rises in due style' is the wordplay.
'rises' shows that the letters should be reversed in order.
'in' is an insertion indicator.
'style' is an anagram indicator (style can mean to shape or design).
'sun' written backwards gives 'nus'.
'due' is an anagram of 'ued'.
'nus' going within 'ued' is 'UNUSED'.
Can you help me to learn more?
(Other definitions for unused that I've seen before include "Neither employed nor second-hand" , "Mint, as new" , "In mint condition" , "factory fresh" , "Not accustomed to" .)
