Building waste covering a wildebeest up (8)
I believe the answer is:
bungalow
'building waste covering a wildebeest up' is the definition.
I can't judge whether this defines the answer.
'building waste covering a wildebeest up' is the wordplay.
'building waste' becomes 'blow' (synonyms. I am not sure about the 'building' bit.).
'covering' indicates putting letters inside.
'wildebeest' becomes 'gnu' (synonyms).
'up' is a reversal indicator (in down clue: letters go upwards).
'a'+'gnu'='agnu'
'agnu' back-to-front is 'unga'.
'blow' going around 'unga' is 'BUNGALOW'.
Can you help me to learn more?
(Other definitions for bungalow that I've seen before include "Single-storey home" , "Type of house" , "A blowgun (anag.)" , "Single storey house" , "One-storeyed house" .)
