Delicately built type destroyed room etc over pub (9)
I believe the answer is:
precedent
'delicately built type' is the definition.
'precedent' can be an answer for 'type' (thesaurus). I am not sure about the 'delicately built' bit.
'destroyed room etc over pub' is the wordplay.
I cannot really understand how this works, but
'room' could be 'rec' (rec room is a kind of room) and 'rec' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for precedent that I've seen before include "Going before" , "Previous instance (as justification)" , "Previous example" , "case one may need to quote" , "Previous case cited in court" .)
