Shabby inside bungalow, or not? (4)
I believe the answer is:
worn
'shabby' is the definition.
(similar in meaning)
'inside bungalow or not?' is the wordplay.
'inside' says the answer is hidden in the clue.
'WORN' is hidden within 'bungalow or not'.
(Other definitions for worn that I've seen before include "Second-hand" , "Showing the effects of use" , "Looking tired and exhausted" , "Threadbare" , "Damaged by long use" .)
