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 one could define the other.
'slut to work again with the polish' is the wordplay.
I cannot really understand how this works, but
an anagram of 'slut' is 'lust' which is located in the answer.
'again' could be 're' (prefix meaning 'again') and 're' is found within 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" .)
