Person leaving one fellow stuck up hazardous construction (8)
I believe the answer is:
firetrap
'person leaving one fellow stuck up' is the definition.
I can't judge whether this definition defines the answer.
'hazardous construction' is the wordplay.
'hazardous' becomes 'fire' (I am not sure about this - if you are sure you should believe this answer much more).
'construction' becomes 'trap' (trap is a kind of construction).
'fire'+'trap'='FIRETRAP'
Can you help me to learn more?
(Other definitions for firetrap that I've seen before include "Unsafe building" , "Building lacking sufficient exits in case of conflagration" , "not built safely" , "Building likely to burn easily" , "Dangerous building in a 20 down" .)
