Dicky learnt duet in cleaner's (10)
I believe the answer is:
laundrette
'cleaner's' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's an association between them I don't understand?
'dicky learnt duet' is the wordplay.
'dicky' indicates anagramming the letters (dicky can mean ill or non-functioning).
'learnt'+'duet'='learntduet'
'learntduet' is an anagram of 'LAUNDRETTE'.
'in' is the link.
Can you help me to learn more?
(Other definitions for laundrette that I've seen before include "Wash-room" , "Washing establishment" , "cleaning outfit" , "On film, mine was beautiful" .)
