Inferior with shoes extremely dirty (6)
I believe the answer is:
shoddy
'inferior' is the definition.
(similar in meaning)
'with shoes extremely dirty' is the wordplay.
'with' says to put letters next to each other.
'shoes' becomes 'shod' (I am not sure about this - if you are sure you should believe this answer much more).
'extremely' suggests removing the centre (only the extremes of the word are used).
'dirty' with its middle taken out is 'dy'.
'shod' next to 'dy' is 'SHODDY'.
Can you help me to learn more?
(Other definitions for shoddy that I've seen before include "Gimcrack" , "Kind of worsted" , "recycled material" , "poor quality fabric" , "Cheap and nasty" .)
