Wheels cleaner with last bits of grime removed (5)
I believe the answer is:
moped
'wheels' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'cleaner with last bits of grime removed' is the wordplay.
'cleaner' becomes 'mop' (something which 'cleans').
'with' means one lot of letters go next to another.
'last bits of' indicates one should take the final letters.
The final letters of 'grime removed' are 'ed'.
'mop'+'ed'='MOPED'
Can you help me to learn more?
(Other definitions for moped that I've seen before include "Despaired" , "means of transport" , "Sulked - form of transport" , "Languidly moved" , "Motor cycle -- sulked" .)
