Something to do with bleach (6)
I believe the answer is:
whiten
'bleach' is the definition.
(I know that bleach is a more specific form of the action the whiten)
'something to do with' is the wordplay.
'something' becomes 'en' (I am not sure about this - if you are sure you should believe this answer much more).
'to' says to put letters next to each other (I've seen this in other clues).
'do' indicates an anagram (solvers must work out or 'do' the anagram puzzle).
'with' anagrammed gives 'whit'.
'en' after 'whit' is 'WHITEN'.
Can you help me to learn more?
(Other definitions for whiten that I've seen before include "Bleach" , "Blanch" , "Become less colourful" , "Turn pale" , "free from guilt" .)
