Putting the slut to work again with the polish (6)
I believe the answer is:
lustre
'putting' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'slut to work again with the polish' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'slut' is 'lust' which is present in the answer.
'again' could be 're' (prefix meaning 'again') and 're' is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'the' acts as a link.
Can you help me to learn more?
(Other definitions for lustre that I've seen before include "Radiance; reflective surface" , "Brilliancy" , "Brilliant quality in a material, porcelain, etc" , "Glory; soft glow" , "Gloss - type of pottery" .)
